Fuel mileage

[konneker143]

I am looking to get better fuel mileage out of my 05 6.0. I was wondering what was the best programmer and any other ways to gain mpg. I have read about the programmers and then read forums. It seems like it is all a big argument to which is best. I am not looking for big crazy power. I have all the power I need to pull what I pull. I am looking to cut down on fuel costs. Any help you can give would be great.

Howdy, and welcome to the ORG.

The only programmer I recommend you installing on a 6.0L is the SCT. The primary reason is that the SCT flash programming will actually tune the TCM for the transmission. Most if not all of the competitors and shift-on-the-fly programmers rely on the transmission relearn for adapting to the new power band. Second, the SCT is custom tuned, meaning tunes are written for your trucks strategy, modifications, and specific goals. The only thing the SCT cannot do is monitor your trucks internals for display, for that I recommend you getting an Edge Insight CS/CTS and at least an EGT probe expansion for running tunes.

If you have questions, let me know.

Most OBD 2 port tuners can tune the trans, not just the SCT. Over the years I have run many 6.0 tuning products (I worked in the truck parts aftermarket industry) I got my best mpg using a hypertech max energy, although now I am using a CTS Evolution with PHP tunes, but getting my best mpg with a stock ECM rollback, PHP FICM rollback, and 3 degrees timing advance programmed via my CTS evo, To tow I would reduce the added timing advance, or, load a tow tune. The extra timing helps because Ford limited the timing advance to control nox emissions, the 6.7 uses Urea injection to control nox instead and gets better mpg than the 6.4 that limited timing, even though both run DPFs.

I would only run a SCT w/ custom tunes


Although the Evolution with PHP tunes is getting more and more popular so if it works out those are the ONLY TWO tuners for the 6oh's

No matter what peoplesay I DO NOT want to test out and replace my tranny cuz I cheaped out and got a crappy tuner!


Just because a tuner/chip nets the BEST mpg for the time being...Doesn't mean it is safe for the engine/tranny


Also, I agree with Colo about getting an insight for gauges



BTW

Read this thread and decide for yourself


Which programmer?

right now hand calculated I'm getting 21hwy, I also try to keep it between 65-70. Thats using IDP's FICM tuner, IDP's street tune (SCT SF3) 4" turbo back (no cat, muffler though) the rest is in my sig, I'm also a maintance nut so it's well taken care of. make sure your injectors are good and FICM voltage is good and the rest should follow.
