DPF Delete

DPF Delete

I have been getting a lot of phone calls at the shop over the past several months from customers wanting to do a DPF delete. If you are reading this then you have probably tried to find the tuner’s needed to perform a DPF delete, and you are having a hard time finding them.

The options are slim to none now days, but it’s not the end of the world. Here’s what you need to realize.

Most customers wanting to do a DPF delete are simply trying to increase fuel economy. Very few are actually worried about performance. There are ways to increase fuel economy without deleting the DPF and EGR systems.

DPF Delete

Clogged Diesel Particulate Filter

Since our shop is not allowed to perform DPF and EGR deletes we have found ways around the problems commonly associated with factory emissions equipment. These solutions are the same for Ford, Chevy and Dodge I will be referring to a 6.7L Cummins we recently did.

The main thing that is going to help with fuel economy is Better Fuel Atomization. What causes the poor fuel economy on these newer trucks is the fact that when the DPF becomes clogged the truck has to force a (Regen) cycle. When your 2007 and newer diesel goes into regen mode, the engine is literally using over a gallon of fuel in a matter of minutes. This is going to affect the overall average fuel economy.

DPF Delete

So the bottom line here is we need to stop the filter from becoming clogged in order to stop the regen cycles.  Poor fuel atomization results in heavy soot content which clogs the DPF.

So how do we get better fuel atomization? Well it’s easier than you may think, most Diesel Programmers increase fuel pressure, that is the easiest way to increase horse power so we start with a good tuner or programmer because increased rail pressure will result in better atomization. There are a lot of different tuners available on the market, but Edge Products makes an Evolution tuner that we have used a lot and the Evolution will work on all 2007 and newer Ford, Chevy and Dodge trucks with a DPF. Auto Agent EzLynk which is another excellent choice and they make one part number that fits all 2011 and newer Ford Diesel Trucks.

Now that we have the required fuel pressure we have to make sure we can keep the injection pump adequately supplied with fuel to prevent cavitation, we always install a FASS Fuel System when we are modifying a DPF equipped truck. There are several reasons we use the FASS but fuel supply is the main reason. To read more on FASS Fuel Systems READ HERE.

Most people associate an aftermarket cold air intake with better performance and fuel economy, and it’s true. An aftermarket cold air intake for your diesel truck is always going to help increase your trucks efficiency. It’s not going to increase fuel economy 3 or 4 miles per gallon like some manufacturers would like you to believe, but there is a mile per gallon to be had there. So for $289 S&B Intakes makes a cold air intake for every diesel truck on the road. It will pay itself off in a couple of months.

DPF Delete


Let’s get one thing out of the way right now. DPF back exhaust systems are a joke! I can’t tell you how many people have bought one online and then called me up to yell at me because it didn’t change the sound of their truck and they didn’t get better mileage….. REALLY! The DPF is what makes your truck quiet, the DPF is what is killing your fuel economy. Hooking up a bigger pipe to the back of the DPF is not going to change anything except the way the tail pipe looks. So if you want a better looking exhaust then buy one, but don’t waste your money on a DPF back exhaust system thinking it is going to change anything else on your truck.

The single most important factor that is going to make your truck perform better is a Water Methanol Injection System. The methanol helps the diesel fuel to achieve a more complete burn so there is no heavy soot going through the exhaust. It also helps to cool the engine down and lower the exhaust gas temperatures. One of the best features though; is the fact that the water methanol is injected into the intake elbow or manifold which cleans any old EGR soot out of the engine. It also keeps the intake clean for the lifespan of the truck. To read more about Water Methanol Injection see my review on that.

So with the lift pump, the tuner, the cold air intake and the water methanol installed your truck will be getting better mileage than a stock 5.9L Cummins that didn’t have emissions systems. You aren’t doing anything illegal and your truck should rarely go through a regen cycle if it does at all. A few local trucks we have done here in Georgia, have reported that it has been over a year since their last regen with these parts installed.

    I have several times I have had to replace the DPF sensor because it goes bad, mainly for the reason the GMC 08 model didn’t come with regen. I had the dealership install sw in June of 2013. I also obtained the CTS Edge to help. The truck is used for pulling horse and some off road toys. The edge shows it goes to regen more than I would like.. What is the cost to do what you suggest. I am for just getting the best use out of my truck without being limited to sensors going bad. This last sensor I tried installing myself forcing a regen, however, the dealership had to do the regen and it took over two hours to clear.

    We could install the FASS fuel system, the water methanol injection and the S&B cold air intake for $3,000 that would be parts and labor.

    Depending on where you are located though I can get you some estimates from local shops. Our shop is located at:

    Lead Foot Diesel Performance
    1991 Leroy Anderson Road

    I like ur ideas and parts, only I am not sure I would be able to use them on my truck. 08 duramax. I have what they call a life time power train warranty. Can’t put snow plow, lift kit, big tires, (cold air intake maybe.) Haven’t ask about this yet. All this voids warranty. You said this is not illegal and lowers temps and keeps things clean.

      I have to deal with those scammers all the time. Not only would everything I listed here void that warranty, it is probably already void if you were to take it in for any major repair. They have never covered anything for any of our customers that have invested in those programs. They will void the warranty over the most absurd things. If you ever went a couple miles over on an oil change, warranty void. If the air filter looks a little dirty, void. If the wrong fluids were ever used during a service, void. The bottom line is, 99% of those “Lifetime Warranties” are a scam. They cost you money and when it comes time to use it, they have so much fine print, they will always get out of helping you with repairs.

      I am sorry for the late reply, for some reason I never received an email notification when you commented. I am sure you have gotten this issue resolved by now. Your issue is either a dirty fuel filter, and the added fuel demand from the programmer made the already dirty filter become an issue. Or the filter was not turned all the way to the locked position when it was installed. I have run into that several times at our shop.

    I have a 2012 Dodge 6.7 Cummins which I love and believe it could be a sound truck but the problem I have with it is it keeps going through O2 sensors and has went through the O2 Sensor module which I am thinking is due to excessive regen and EGR with DPF issues as I live in town and can’t drive it long enough or fast enough to get the proper regen done all the time. I was thinking the deleting was the only option but you have me rethinking this issue and it makes complete sense to me. I live in Northern Indiana if you know of a reputable shop which could do this for I would appreciate the info and thank you for the informative article.

      Fuel economy gains will always be noticed, no matter the mileage. Generally you will see 4-6 miles per gallon increase, but that all depends on how you are driving the truck.

      With the tuner, intake and exhaust installed you will be around 530 hp at the rear tires, the water methanol will give you an additional 60-70 hp depending on how you set up the controller.

      The Amerihood will look neat, and will certainly help keep the temperatures down under the hood, but it’s not going to change much in the way of fuel economy. The scoops are nowhere near the actual air intake. The Air Raid intake will certainly help more than the hood though.

    I have a 2012 f250 with 117k, I currently have an sb cai and an SCT tuner with a custom tinge from innovative diesel. The truck runs great until I put the hammer down and then it will take off but within a few seconds it will fall flat (like no fuel). It had done this with different tunes. I am currently looking to do the dpf delete and would really like to know if it will increase longevity. The sound and power are secondary but nice. V/r Scott C

      If you are running the SCT with custom tunes and a stock exhaust, it will fall off like you are describing, because the tuner is reducing fuel to avoid clogging up the Diesel Particulate Filter. You will also experience more regen cycles (Cleaning Exhaust) because of the increased particulate matter caused by aggressive custom tuning.

      If you are thinking about installing an aftermarket exhaust, there is a new tuning device that will be available for purchase in a couple of weeks. It is a device that plugs into your OBD2 port called an EzLynk, we are BETA testing this tuning device right now on one of our shop trucks, it works very well. We can shift through the power levels on the fly with an app on our iPhone called AutoAgent. You can also watch all the engine vitals on the screen of your iPhone, iPod or iPad device. If you get more serious about moving forward with this feel free to give me a call at the shop and I will explain in more detail how all of this works. 770-267-3322

I was willing to play by the rules but enough is enough. I need to get rid of all of this so I can actually depend on my huge investment. I don’t necessarily need more power but I understand I have to have a tuner to delete the codes. What exhaust will work best and what tuner. Also if I do a complete exhaust will my exhaust brake still work? Any info would be great thanks.

I was looking at Edge and Minimax tuners but all the mechanics local have been telling me those tuners are not good ones. That the minimax is only a bullydog with new stickers. They recommend the Efilive? All this being said I can get the full delete and all for 2800 including labor is this a bad idea or bad price? What do you recommend?

      The H&S Mini Maxx is an excellent tuner. Whoever told you it is no good has some kind of agenda. EFI Live works just fine as well. I personally prefer the Mini Maxx because it has the defuel settings built into it. These settings will help protect the engine and transmission from damage caused by high fluid temperatures.

      Increasing fuel pressure, removing air from the fuel and fine tuning the timing and high pressure injection pump will certainly increase fuel economy on any diesel engine. That being said I don’t know of any companies offering those modifications for your specific vehicle.

    2006 6.0 Powerstroke in F250. Question is, if you were to just cut through the up pipe leading to the EGR cooler with say a sawsall, and then insert small plate steel that size, and weld back together with it as a block, wouldn’t that do same as EGR Delete. Then could just run the coolant around the EGR Cooler there, and all would be good?

    Hello Vinney,

    I have a 2011 Dodge 3500 with Cummins Diesel engine. Long story short, the truck has been in the shop numerous times because of the engine light coming on and in all cases it had to do with soot on the oxygen sensorsr. Last summer, and just two weeks before my warrant ran out, engine light on again. This time they suspected the injectors were pushing too much fuel. They tested the injectors and two were doing just that and were replaced. A short time later the engine light comes back on again and same problem with the exhaust system. The dealer pushed the issue with Chrysler and Chrysler agreed to replace the whole exhaust system. That was in July 2016. Every thing was fine until a few weeks ago and the engine light came on. Sure enough, another sooted up sensor. They again pulled the injectors and they were fine. The dealer put me in what is called the Gold Star program with Chrysler, so the whole thing is going up to their engineers. After I picked the truck up with the last one, the engine light came on about a block away so I returned to the dealer and they found another bad sensor in the exhaust system. It will take a couple of weeks to hear back from Chrysler. The dealer has been outstanding in trying to resolve this problem, but I have little faith the problem is resolvable. I am on the verge of putting in a delete kt. But, I am also adverse to doing something illegal that may come back to bite me at some point in the future. I found your article on line yesterday. I live in Post Falls Idaho, near Spokane WA. Will this system you discuss in your article solve my problem? Any help or advice is appreciated. Thanks. Mike

    Hey brother, I have a stock 2012lml w 100k on it. I have recently been studying all this noise about emissions and the harmful side effects it has on our trucks and our wallets! I mean comon, use DEF to reduce emissions for the environment but package the fluid in millions of plastic containers that can’t even be recycled. Hmm. Liberals.

    We were recently stranded hours from home pulling a 10k lb travel trailer because of DEF sensors, I was mad AND let down. Anyway I don’t care about 800hp but I want my truck to be reliable for ever if possible. What’s a good basic package that would free it up and make it breathe like the diesel gods intended it to?

      It is very disappointing that the EPA has taken what used to be a very reliable and powerful engine and smoothered it to the point they simply will never work properly. They are lining their pockets with our hard earned money. You can generally get all the parts plus labor for around $3,600 but there are a hundred ways to skin that cat, different brand parts, varying labor rates etc.

    Hi Vinny,

    I am in Detroit, MI area, looking for some good diesel people to get in touch with, I am south of the city and close to northern Ohio as well, I am looking at the 2017 trucks and not so quick to pull the trigger due to the poor MPG I am seeing, plus problems with sensors, but not a big diesel guy, but need to the extra truck to pull the camper, and also some ATV’s in the bed at the same time which is not a good combo in the 1/2 ton truck, if you can point me to some people in my area, to chat with that would be awesome!

      Yes you can, when you select main menu, you will then select “install download” you will then be asked to confirm what truck you are flashing, then it will ask you a few more questions and there will be a question asking if the emissions equipment is present or removed, select “present”

    Hey Vinny, thanks for the solid info in this forum. I’m in western WA, looking to do a EGR/DEF delete, PCV reroute and possibly replacing the CP4 with a tried and true CP3. I shot an email over to Dynomite Diesel to see if they can do the work. Any other recos on shops around these parts?

      There are a lot of good shops in that area, I used to be the sales manager at Alligator Performance in CDA, I don’t know if they are still wrenching on trucks or just focusing on online sales. They would be worth a shot, DDP is a great group of guys, I don’t know if they are wrenching on trucks at their CDA location. I think that may just be their fuel shop, I know their Monroe WA shop does wrench on trucks.

      CN Diesel Performance in Postfalls ID is a great shop I used to work at back in the day. Nick Bowlin is the owner, Casey is the shop foreman. There have been a few new shops that have popped up in Spokane since I moved to Georgia, I haven’t heard of good or bads about any of them.

      I have had a lot of issues with those CP3 conversions on the LML’s mainly the tuning side of it. We won’t do them anymore for that reason. We have found that adding a Fass fuel system does fix the CP4 failures.

    Vinny, A little background first so you know were I’m come from. I tow daily operating a small construction company. I bought a 2015 Silverado with a 6L gas engine because I was so scared of all the new diesel engine problems. As my company grew so did the trailers and now I’m getting 6 MPG with gasser. I’m in the process of trading the Chevy for a 2015 Ram 2500/ Cummins. Of course I’m reading a lot about clogged this and sooted that problems. I’ve also read all the delete articles but I already have enough problems with the EPA in my industry and don’t need more problems and don’t want to devalue my investment. Just read your article on DPF delete and I’m interest. I need a dependable bullet proof truck with good MPG while towing daily to keep my business running. Would love to hear your opinion. Here are my Facts. I live Fenton MO just south of St. Louis, 2015 Ram 2500 w/ Cummins everything is currently stock but with be adding larger tires and level, Tow between 3 and 5 tons on work days. Thanks you

      Out of all the new diesel trucks, we have fewer problems out of the Dodge emissions parts then we do with the Chevy’s and Fords. GM has been a real pain, their DEF tanks hang low and we are constantly replacing the tanks when customers go off road and the tank hits something, that’s just a piss poor design. We also have a lot of issues with their urea pumps and sensors failing.

      The 6.7 Powerstroke is probably the best diesel engine ever designed, for a lot of different reasons, including performance, design, and the really made them easy to work on. We do have quite a few issues with their DEF systems though. For one, they put the DEF fill port right next to the diesel fuel port. I can’t even tell you how many customers have mistakenly poured the DEF fluid in their fuel tank and destroyed their entire fuel system in the process. We also have to replace a lot of the DEF sensors, pumps, reductant heaters etc.

      We really haven’t had many issues with the newer Dodges as far as their emissions systems go. I will tell you this, their automatic transmissions are JUNK! With most things in this industry, there’s always weak inferior parts, but we can usually build them better or replace them all together with a better, stronger aftermarket part. That is not the case with the 68RFE transmission or the Aisin transmission. We can beef the 68RFE up a little better than stock, but they still eventually fail. The Aisin is quite simply, a lost cause. It should have never existed. I have customers that have replaced 5 or 6 Aisins before finally giving up on the truck. All that being sad, I would try your hardest to find a truck with the G56 manual trans, no matter how much you may not want to shift gears, it will save you tens of thousands of dollars in the future.

      Not much has changed on the 6.7 Cummins since it was introduced in 2007.5 I had an 08. I had some issues with it in the beginning. The stock turbo failed around 38,000 miles and the head gasket failed. They fixed it under warranty and I bought a set of ARP studs that the dealership was willing to install when they did the repair. At 55,000 miles the head gasket failed again, they fixed it again under warranty. At 75,000 miles the turbo failed again as well as the head gasket. At this point the dealership said I was towing too heavy and that’s why it kept failing.

      I was towing heavy, I won’t lie. That truck spent every day of it’s life with a 35′ triple axle goose neck behind it. Some days loaded down with 20 round bales of hay, some days with logs and timbers. I did end up getting rid of the EGR on that truck as the dealership recommended. It did resolve the head gasket issues.

      If you aren’t towing heavy, you should be fine doing the upgrades I mentioned here. The Fass fuel system is a must, it doesn’t just filter the fuel, it conditions the fuel, removing all air, dirt and water. The factory fuel system doesn’t do this. The injection system on these newer diesels operates above 20,000 PSI one little air bubble in the fuel can turn into catastrophic failure very quickly. It will also help with fuel economy as we are better atomizing the fuel for a more complete burn.

      Water Methanol Injection is simply amazing. It cleans the engine internally, cools exhaust gas temperatures (EGT’s) and offers a noticeable boost in performance. If you have any further questions about these upgrades, feel free to give me a call at 77-267-0773 or email me at

    Great article! Have 2007.5 GMC lmm duramax and came with economy EFI tune installed. Everything else is stock. The truck has over 250000 kms and want to do what is best for reliability and fuel economy. Used mainly for pulling rv trailers below 8000 Lbs. The truck recently passed emission test here in Ontario so I will not need to have another for 2 years. Some local shops have told me that recent trucks that they have performed egr deletes and removed dpf etc. have failed. I am planning on cutting off dpf and installing flo-pro 4″stainless delete pipe only and keeping my dpf with ability to bolt back on if needed for future passing of test. Beepin JOKE! EGR blocker plate and not doing egr delete, but installing a tuner/programmer with the ability to delete emission software with capability to re-install so I can go back and forth with dpf and non. Can this be done with the H&S mini max and use this only for that purpose? If it cannot do you know of other tuners with this capability that you can recommend? With tuners ability to remove emissions or shut-off , do you need the blocker plate installed? Will this affect my current EFI tune in anyway? If this set-up works do you recommend unplugging the egr as well? I am also interested in doing a little more research into your water methanol idea instead of above mentioned, but want to see how much this will cost etc. Any additional info added will greatly be appreciated

    Hi Vinny,
    I have a 2014 f250 KR with a 6.7 diesel and it has just over 78k. I use it to pull about a 7k trailer for close to half of its used miles. I also pull a 10k backhoe about 1 or 2 times a year and otherwise its a mix of highway and backroad use. I get a combined mpg of 14 even. I live in NW CT and would like to know if there is a shop in my area that can do the upgrades that you are suggesting? I want to keep it legal so a delete is not an option. I also don’t want to risk damaging the motor because I really want to keep this truck ( I bought it new). I am in the stage of searching for the best options to gain MPG but won’t pull the trigger until I hit the 100K mark sometime toward the end of next year. I don’t want to risk loosing the warranty on this 15k motor.
    Thanks you for any help you can offer and for all the above answers to others questions in the past,

    Hi, I just purchased a 2017 ram 5500. I tow a 3 axle gn trailer with it 99.9% of the time and loaded to the max over 75% of the time. I’ve heard both sides of the upgrade routes, deletes vs fuel & tuning upgrades. I know the C&C Cummins are tuned differently to begin with.

    1. Are they simply “de-tuned” as many suggest or are they actually tuned different due to the MAJOR drivetrain & gearing differences. The 5500 I own has Dana 120s with a Borg Warner transfer case. 4.88 gears and the Aisin tranny. I know your views on the Aisin but it’s what I have and can’t change that.

    2. I have just over 8k on the truck now. Loaded I average 7.5 mpg. That’s at 35 to 38k gcvw. If I’m going through the mountains, it may drop slightly, but the biggest factor by far is my speed. If I stay at 60 mph or lower, I can increase by 1 mpg easily. That’s huge when averaging 7 to 8 mpg. So, fuel economy is a big deal, but towing power is right up there. I have quotes on EFLivr with FassFuel system OR full deletes with exhaust & 5 stage on the fly switchable tuning. Both are comparable in cost, the latter being an additional 1000 for FassFuel added. So tje queation is this, what woukd you do? I’m looking for longevity, followed by fuel exonomy then towing power. I know the EPA has these diesels choked back, and my gut says get that crap off, but IF the difference is nominal, I would consider tuning with fuel system upgrade.


    Best regards,

      1. They are tuned very differently as the transmission is totally different, the EGR and DPF are totally different in the way they are designed and the way they function. They are de-tuned in a sense, to keep emissions lower as the 4500 and 5500’s are consider commercial vehicles. As commercial vehicles it is assumed that they will be logging more overall engine hours than a regular pickup truck, therefore it is assumed that they will leave a much larger “carbon footprint” this is the main reason for their lower overall power output.

      2. EFI Live tuning with the addition or an aftermarket turbo back exhaust and a Fass fuel system is going to greatly increase the engine longevity as well as increase engine efficiency. If that is a viable option for you, that is the route you need to go. The Aisin transmission is perfectly fine in stock form and very reliable, the main issue I have with them, is there’s no aftermarket support for them and we have found an increase of only 80hp will highlight their weakness

About 70% empty hwy use and 30% of the time in summer pulling a 16,000 lb 5th wheel TT through the mountains. I don’t want to void warranty and prefer to shell out the cash in stages, but need better mpg. I’m thinking to start with the FASS but which one? I’ve seen the Titanium and one website referenced a H.D. If the FASS is the first step, what do you recommend next?

But pulling my 5th Wheel, mileage has gone from 11 in the past to down to 8… No good!!! I live in Long Island NY. Total stock truck by the way. Heading to Tennessee end of July so want to fix this before that. Also, truck seems to regen more and going through DEF more. Truck has 116K miles. Any help is greatly appreciated, plus a reputable shop would be nice, since the dealer cant find anything.

      Dealership techs are not problem solvers, they are simple code readers, and parts changers. If the truck doesn’t have any check engine lights, they simply assume everything is in good working order. The issue you are having is being caused by the diesel particulate filter being clogged. It’s obviously not totally clogged as the truck still runs and drives fine. But think of it as a sewer pipe that is 3 inches around and there’s so much crap stuck inside that the 3 inch opening is now only 1 1/2 inches, the toilet still flushes, but not as good as it did when that pipe was new. Unfortunately we can’t run a pipe cleaner through your diesel particulate filter to scrub it out.

      All you can do at this point is replace the filter and start back with a brand new sewer pipe.

      The reason this happens: when your truck was new the filter was spotless inside, unlike a sewer pipe there’s no water running through it to keep exhaust soot and particulates from building up, as the filter becomes clogged with soot, it relies on a regen cycle to clean it out, a combination of things take place during regen. DEF (Diesel Exhaust Fluid) is injected into the exhaust to help clean out soot, while the engine starts over fueling to create heat and pressure from normal driving to force soot build up out. Every time your truck goes through regen it takes about 15 minutes of “normal” highway driving (65mph or faster) to clean out the filter. Even if this cycle performs flawlessly there is always a little bit of soot left behind. After thousands of miles and hundreds of regens, this little bit of build up turns into a lot of build up. This is where you are at currently, so the truck is seeing a lack of flow through the exhaust via the pressure and temperature sensors in the exhaust pipe and its triggering more frequent regen cycles. This is what’s hurting your mileage, every time the truck goes through regen you are basically wasting a half gallon of fuel.

      A brand new exhaust filter will help your mileage, I promise. If you have any further questions, feel free to give me a call at the shop. Lead Foot Diesel Performance 770-267-0805 – Vinny

      Charlie, you can do the head studs at any time. Some people choose to wait until it is an issue, and some people know of the issues and get the head studs done before it becomes an issue. Either way, it doesn’t matter. Some shops use scare tactics to try and get you in their door, the bottom line is, all 6.0L’s eventually have head gasket failure, whether it happens at 40,000 miles or 400,000 miles. Here is a link to what we do on them, with an explanation of why we are doing what we do.

    Great Article Vinny. Thanks for the education. I read all of the comments and questions and saw your “Aisin” bash. eeeekkkk.

    Bought my 2015 RAM 3500 DRW AISIN used about 15k ago. I only tow a 13,000 5th wheel twice per month about 200 miles and the rest of my driving is 90% freeway (65 to 70mph) and 10% city.

    I simply want the best fuel economy I can scavenge from this thing. Does your suggested package:
    FASS Fuel system, S&B CAI, Water Methanol Injection system, Edge Evolution
    Sound like my best bet. Any issues with any of this with AISIN owners? Again, I am a feather foot and don’t mind not increasing HP or torque. Just looking to scavenge diesel. I only average 15k to 20k miles per year.

      I’m not so much “bashing” on the Aisin, I’m simply frustrated with it’s lack of performance. Chrysler has had a 30 year reputation of using crappy transmissions in their diesel trucks. Each new year, each new body style, each engine upgrade I keep finding myself on the edge of my seat chewing my fingernails off praying, hoping they will finally give us a transmission worth it mustard. Yet here we are in 2017 with two horrible options for automatic transmissions on the Ram platform. The Aisin will not hold an extra 80 horse power without eating its self from the inside out. The 68RFE isn’t much better, but at least there are some options to beef it up and make it a little stronger.

      I could ramble on all day about transmissions. To answer your fuel economy questions, yes the parts I’ve listed would net you some substantial fuel economy gains. I shot you an email as well.

    DPF and EGR deletes might be illegal Inn washington state, but in Oklahoma where I live we have NO emissions. This means since my Ram got 100k miles, the delete is done. MPG increased from 11 city to 19.8 city. As always, you can’t trust the government with anything. Thanks EPA!

    I have a 2014 RAM with a 6.7 Cummins, just over 70,000 miles. Used to NEVER have regen issues. A factory recall was issued a while back and dealer replaced the DPF, this was a year or so ago. The first regen after replacement happened in a normal fashion and was completed in just a few miles at average speed. The next one was actually a few months later and took a hundred or so miles to complete. Now the third showed up a week and a half ago, to date error message still says, exhaust regeneration in process – DPF is 100% full. 200+ miles driven with the first 100 miles being hard driven. No power down, plenty of get up and go with no noticeable affect on performance at all. Is running great, as good as ever actually. Long story short, seems now that regen is not going to complete, at least per the message display. Could this error message possibly be incorrect as a result of a bad sensor or other component within the system? Just seems extremely odd that all of a sudden regen is needed on a regular short term basis, and now it seemingly is not taking place at all, or as it should. My fuel economy is great, performance is great, so I’m not after enhancements in that regard, just need this “all of a sudden regularly needed REGEN issue resolved.” Thanks for your thoughts.

My husband has been noticing his truck doesn’t seem to be performing as well as it used to and wants to see if he can fix it. Thank you for the information about unclogging the filter and remove the heavy soot clogging it.

    17 ram 2500. All stock. What could I do to it and not break the bank. Has warranty but they claim as long as I don’t go crazy with it. They don’t care what I add. Several customers of them have done all the things I’ve considered and no problems. Been considering a performance kit. Cold air. Mini Maxx Tuners. Exhaust kit. Gets pretty good mpg now. 18 town. 20 Highway. But I’m sure we could do better. I only pull about 7500 lbs. want even better sound and economy.

    I have a 16 ram 3500 and recently towed my 14k 5th wheel 1400 miles ( total 14k miles on the truck). On the first half, I got 9.1 mpg and went through a full tank of DEF! on my return trip I got 9.3 mph and only used about 1/4 tank of DEF. My 5.9 got much better mileage pulling the same trailer… I am wondering if there is a reasonable solution and / or is there something wrong with this 16 ram 3500. I might ass that no mil lights came on. I need to get better mileage than this. Around town, I get 13.7 driving like miss daisy. Any Ideas on what to do next?

    Vinny, I just bought a factory stock 2012 Ram 2500 6.7 Cummins and it’s getting about 15 mpg. I would like to change the exhaust to delete the converters. I’m new the the whole delete and tuning and would like some advise to what you suggest and if you think 20 mpg is attainable for my 6.7 Cummins? Any advise would be appreciated!

    Thanks, David

    Hi Vinny,

    I’m in the market for a new truck within the next three years (gotta wait till my son gets out of daycare). I currently have a half ton, but I’m looking at upgrading to a 3/4 or 1 ton, probably 3/4 as ride quality will be better (on ram). So I have been doing quite a bit of research on trucks. I’m on the fence between purchasing a diesel or a 6.4 hemi. My father has a 2017 ram 2500 with 6.7 Cummins and likes it. He pulls a travel trailer. He has not had any issues, but he only has 30,000 miles on it. I don’t mind paying the extra up front cost of a Diesel engine since it’s more capable and typically gets better gas mileage. However, my concern is the added maintenance cost of diesel trucks particularly with the epa parts. I’ve read lots of information online about various problems associated with egr, dpf, etc…. I also noticed that you lose about 800-1000 pounds of payload when upgrading to a Diesel engine (due to weight of engine I guess). So I have a few questions for you:

    1. Given the fact that I only tow my boat every once and a while and will primarily be using my truck as a daily driver (I have a short 8 mile drive to work rural driving mainly, but not highway). I also haul various items (lumber, hunting accessories, other building project related items ,but not daily) Do you think I would be better off just going with the 6.4 hemi? I have driven my father’s truck and love the way the diesel performs. It has loads of torque and gets terrific millage. He has had as much as 22 mpg on the highway unloaded (his truck is completely stock). But I wonder if the extra cost, extra maintenance, and extra cost of maintenance/problems is worth it. I just don’t know enough about diesels to decide. I’m hoping you could provide some insight.

    2. I have read that on the new 2020 Rams, they may be pairing them with an 8 speed transmission rather than the current 6 speed. I also read some speculation that the new cummins 6.7 will do away with the EGR completely and rely on other methods to meet EPA requirements. Do you think this will occur and is the absence of an EGR a game changer in terms of reliability, maintenance, and performance?

    3. If I did decide on a diesel truck, I’m not concerned about adding power or torque. I’m happy with the stock 800 ft pounds and 370 hp. That is more than enough for me. I’m more interested in reliability, MPG, and ultimately keeping the cost of ownership down. I’ve been an amsoil customer now for a while and I read on their site that they recommend an oil bypass system. Do you agree? Without deleting EPA requirements, what other suggestions to you have for improving reliability, MPG, and longevity? I see from this article that you recommend a Water Methanol Injection System. But wouldn’t that require a special tune? I’d be concerned about defecting the warranty and also potential computer issues in the future after altering the vehicle’s computer system.

    4. I live in MD, and my county does not do emissions, do you recommend completely doing away with all EPA parts? Does that cause the diesel smell to be more noticeable?

    5. On the ram cummins, it recommends oil changes at every 10,000 miles or 1 year. I’ve read some comments on line from various people that this may be too long. What do you think?

    Sorry, for so many questions, but any insight that you could provide would be helpful.

    Thanks for you time.

      Thank you for reaching out to me with these questions, you have some good ones and I am happy to address them.

      1. Given the fact that I only tow my boat every once and a while and will primarily be using my truck as a daily driver (I have a short 8 mile drive to work rural driving mainly, but not highway). I also haul various items (lumber, hunting accessories, other building project related items ,but not daily) Do you think I would be better off just going with the 6.4 hemi? I have driven my father’s truck and love the way the diesel performs. It has loads of torque and gets terrific millage.

I just don’t know enough about diesels to decide. I’m hoping you could provide some insight.

      You are in Maryland and we are in GA, so my answer to this question in no way benefits me, this is simply my un-biased response based off years of experience in this field. The diesel world is constantly changing due to federal emissions mandates. So to say one auto manufacturer’s engine is better than another’s, is no longer the case. As of now all my recommendations are based off who has designed the least problematic emissions hardware. And know this, IT IS ALL PROBLEMATIC!

      With what you are looking to do with the truck, get the diesel. The MASSIVE difference in fuel economy alone is going to offset any potential maintenance expenses. The commuting is where the diesel is going to shine over the Hemi believe it or not. Either engine will tow your boat a couple times a year, it’s all that driving in between were a diesel is going to be the better option.

      In years past, I would be pushing you to get the “Cummins” however, that is no longer the best diesel engine on the market. When Dodge went away from the tried and true 5.9L in 2007 and adopted the 6.7L Cummins, they became very problematic. We work on roughly 70-90 trucks a week here in our 30,000 square foot diesel shop. Everything I am telling you is based off massive volume and tons of experience. The 6.7L Cummins have a major design flaw in the block that causes hot spots in the head gasket. They blow head gaskets worse than a 6.0L powerstroke. And since it’s a design flaw with the block, we can’t “FIX” it like we can on the 6.0L’s

      While not everyone experiences a blown head gasket with their 6.7L Cummins, it’s a 9 out of 10 kind of scenario. The best diesel engine currently on the market, with the least amount of issues with the factory emissions equipment is the new 6.7L Ford Powerstrokes. Aside from emissions equipment, it’s just a very well put together engine with no major issues.

      Your average Gas engine is pretty well wore out at 200,000 miles and are costly to replace. Your average diesel engine is just getting broken in at 200,000 miles. I have several customers already over the 600,000 mile mark with their 6.7L Powerstrokes and still going strong with no major issues.

      2. I have read that on the new 2020 Rams, they may be pairing them with an 8 speed transmission rather than the current 6 speed. I also read some speculation that the new cummins 6.7 will do away with the EGR completely and rely on other methods to meet EPA requirements. Do you think this will occur and is the absence of an EGR a game changer in terms of reliability, maintenance, and performance?

      If they have found a way around the EGR, all I can say is, “It’s about damned time!” What a joke, there’s a million different ways to make these engines run clean, besides making them choke down their own exhaust. EGR is the most retarded thing I have ever seen in the diesel world. Yes, if they get rid of the EGR those engines will run a whole lot better. Honestly they need to get rid of EGR, get rid of the DPF and get rid of the DEF, replace all this BS with a really refined tune and a factory form of water methanol injection. It’s windshield washer fluid, it’s cheaper than exhaust fluid and efficient!

      An 8 speed trans would be the cats meow!!!

      3. If I did decide on a diesel truck, I’m not concerned about adding power or torque. I’m happy with the stock 800 ft pounds and 370 hp. That is more than enough for me. I’m more interested in reliability, MPG, and ultimately keeping the cost of ownership down.

But wouldn’t that require a special tune? I’d be concerned about defecting the warranty and also potential computer issues in the future after altering the vehicle’s computer system.

      Water Methanol doesn’t require custom tuning at all. It’s really a very reliable and brilliant power adder. It helps clean heavy carbon deposits out of the engine that are caused by the EGR. It can also reduce the number of regeneration cycles the exhaust has to go through, which will result in a fuel economy gain.

      Every time one of these new diesels goes into regen, it consumes about a gallon and a half of fuel in only 15 minutes. If we can cut back those cycles is will increase fuel economy.

      Water methanol helps with fuel atomization. That means we are getting a more complete burn of the fuel being injected into the engine. a more complete burn of the fuel means fewer diesel particulates, which means the exhaust filter is not becoming clogged up, so it doesn’t require a regen cycle.

      These diesel engines go for 600,000+ miles with nothing other than the factory oil filter, the oil bypass systems are problematic, leaky and completely unnecessary.

      4. I live in MD, and my county does not do emissions, do you recommend completely doing away with all EPA parts? Does that cause the diesel smell to be more noticeable?

      I can’t recommend the removal of any federal emissions equipment, professionally. All I can tell you is it is a failed system. The big 3 auto manufacturers designed a very faulty system, with lots of moving parts and it doesn’t work. Removal of those systems is the only way to “FIX” those issues. The replacement of those faulty parts is insanity (doing the same thing twice, expecting a different result)

      5. On the ram cummins, it recommends oil changes at every 10,000 miles or 1 year. I’ve read some comments on line from various people that this may be too long. What do you think?

      I was a hot shot trucker for many years out west and I ran a fleet of 5.9L Cummins equipped Dodge Rams, I was running Schaeffer’s synthetic oil in those trucks and I was sending oil samples to Caterpillar every time I changed my oil to ensure there was no internal engine damage taking place. Running conventional oil we would see high zinc levels at around 6,000 miles and they would recommend I change it. With the Schaeffer’s oil everything looked perfect at 10,000 intervals. So that’s the oil I ran for many years. So to answer your question, not all oils are created equal, use a good quality oil and yes, the 10,000 mile interval should be fine.

    I am in the san Francisco bay area. I have a 2000 f350 7.3 6 speed with 500,000 plus miles. Any good shops in the area? I have been doing my own repairs and maintenance but its very busy at work and i need someone who will be straight with me. No patience for posers.

      Water methanol injection is 50 state legal and meets all CARB and EPA requirements, I don’t see any reason you can’t have a system installed locally. Feel free to give me a call if you do get a system installed and have questions with fine tuning it. 770-267-3322

    I know you have probably mentioned this at some point, but could you please, again, give your recommendation of items to delete, not delete, and/or add for a 2012 Ram 3500 6.7 DRW? We full-time in our 5th wheel therefore we tow often so we want our truck to last and be the most efficient. Thanks for your time!

      I can’t recommend deleting anything. The EGR and DPF are “federal emissions components” deleting them is illegal in all 50 states. However, the EPA’s official stand point in such things, is if the parts being used to remove a faulty factory component are tested and approved with a CARB certification they will allow a pass. If you can find a manufacturer that makes an EGR delete that is tested and approved then you would be fine to install it, same goes for the exhaust. There are companies out there going through such testing as we speak and some as getting the pass, while others get the knife. This next couple of years is going to be very interesting in the diesel performance industry.

    I have a 2011 F250 6.7 turbo diesel with an H&S mini max tuner an afe cold air kit / def and egr deleted. I have 240000 miles on it and its getting 15.4 mph on average. 35″ tires 6″ lift. I’m running performance mode on the tuner and run about 70 mph, I bought the truck as is and am new to diesels. It runs strong but seems to stumble a bit out of the hole. Thanks any information is appreciated

      At 240,000 miles I would be looking at the low pressure fuel pump. They will start getting weak and will definitely cause a hesitation and usually a lose of fuel economy.
