Best 6.0L Powerstroke Tuner

Best 6.0 Powerstroke Tuner

There are a lot of different performance tuners on the market today, some work great and some of them are absolutely worthless. I refuse to bash on any manufacturers so lets just put it this way. I have installed every single aftermarket diesel tuner available.

If you don’t see the tuner you were wondering about listed here, it’s because that tuner is junk. Either the engine tuning is horrible or the transmission tuning is horrible. That being said I have found that some manufacturers excel on some trucks but not others. So just because I don’t recommend a tuner from a certain company doesn’t mean I wouldn’t recommend it for any other diesel engine.

When it comes to the 6.0L Powerstroke engine I prefer the SCT platforms. Whether you get the 7015 handheld, or the SCT 5015 with the LCD touch screen. The tuning is the same.

The 7015 comes with 4 canned tunes and they are excellent. The transmission tuning is flawless and the engine tuning is very smooth and efficient. It can hold up to 10 custom tunes and there are some great custom tune guys out there but there are also people that like to call themselves tuners that have no idea what they are doing. So be very careful and do your research before trusting someone to tune your engine.



The SCT 5015 Live Wire TS is also a nice tuner. I run one in my personal 2003 6.0L and I really like being able to monitor ICP pressure, actual coolant temperature, actual oil temperature and drive pressure. There are many different parameters you can monitor and I like having those options at my finger tips.

These tuners are very popular in the 6.0 world not only because they have extremely smooth power and good transmission tuning, but also because they give the end user the ability to shut off the check engine light associated with the check engine codes P0401 and P0404. EGR codes are very common with the 6.0L Powerstroke, whether you replace it, plug it, block it or get rid of it, those codes and check engine lights can be very annoying.

It’s very simple for the EPA to push this legislation upon diesel engine manufacturers. I wish they would realize what EGR has done to what used to be a very reliable and efficient line of diesel engines. International never really had any major issues with their 7.3L platform, guess what, they had no EGR on the 7.3L.

As soon as the 6.0 became Fords new power plant EGR was enforced by the EPA to clean up the NOX emissions, that engine has one of the worst reputations of all time. Followed by the 6.4L which has an even worse reputation due to all of the problems associated with the EGR coolers clogging, cracking and failing.

EGR is never going to work on a diesel engine. When the manufacturers realize they can clean up NOX emissions with simple water injection then we can again purchase trucks with Diesel engines that will be clean burning and very efficient.

    AS far as the Transmission tuning you say is ‘Flawless” did you hook up a pressure gauge to the Line pressure port on the transmission? I already know the answer, as you did not or you could not say that it is flawless, the factory loaded SCT tunes do NOT control line pressure properly. the pressure at WOT in drive is Lower than stock, which Will cause transmission failure.
