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
HERE IS A CLOGGED INTAKE FROM AN LMM DURAMAX BEFORE WE INSTALLED THE WATER METHANOL ON THE TRUCK

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 Washington state 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.

    Sonja,

    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
    Monroe, GA 30655

    If you aren’t local to us shoot me an email and I will find a shop closer to you. I will also call them for you to make sure I am comfortable with their ability to properly install these parts needed to make your Duramax Diesel truck more reliable and efficient.

    I’ve got a 2013 Ford F250 6.7 diesel. I wanna pull all the EPA BS. I’d like to pull the exhaust and put a 6inch on. But it’s sounding like that’s illegal? What would is cost to do all the upgrades you mentioned on my truck plus exhaust? And I’m not local, but I will come to you if need be and stay in a hotel while ya fix my baby up.

    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. Have u worked with life time power train warranty companies? I haven’t won an arguememt with them yet:-( 🙁 🙁 🙁 🙁

      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.

    I just bought a 2015 6.6L Denali and yes I got all the warranties. However, I am looking at doing some upgrades even thou I dont know all that much. Here is what I was thinking of doing for now…
    DPF, DEF, CAT and EGR Delete with a larger no muffler pipe and cold air… Thoughts? even more so, what are the better parts and companies to go wtih? Do the new 15s still need the FASS Pump?

      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

      Scott,

      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 just bought a 2013 duramax. I have already spent $2,000 changing nox sensors, def heater and dpf injector and my truck still will not stop saying that I have poor quality def. 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 haven’t had much luck with the RaceMe tuners. The trucks will constantly go into regen and won’t come back out of regen. Even when you are running an aftermarket exhaust. I have had much better luck with the H&S Mini Maxx or EFI Live tuning.

      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?

      It would stay in regen as the sensors wouldn’t be measuring the same readings that they are normally calibrated to read. Both pressure and temperature would be reading low which would put the truck into reduced engine power mode.

Never having owned a diesel and reading about the spontaneous shut down problems and the “death shudder” we are nervous about this purchase. This aftermarket modification sounds like the solution. you mentioned WA state in your article so I asked if you have a place in WA..we live north of Seattle (but voted Trump).

    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? I know a lift pump is a must to help my retard step child CP4.

      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.

      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 vinny@leadfootdiesel.com

    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,
    Paul

    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.

    Thoughts?

    Best regards,

    Craig

      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

    Hi Vinny,

    I’m interested in increasing my mpg. I have a 2016 Ram 3500 6.7 Dually aisin transmission with 410 gears. I tow a 20,000 toyhauler thru out the summer months. I get about 15 mpg with out 5th wheel and 8 mpg with 5thwheel. What would you recommend?

    Thank you for your help!

    Vinny,
    Have a 2013 ram 3500 diesel dually, aisin trans, and 4:10 gears with 32K miles. So far not one problem. 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?

    Hi Vinny. Great reading your thread. I have a 2011 6.7L F-250 that recently the mileage has dropped significantly. Brought into Ford service 3X and they say nothing is wrong. 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.

      Rob,

      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.
