08 6.4 mileage

[kimmer]

I know you guys have a tuner coming out soon for the new 6.4 powerstroke, what are you guys seeing for increase in mileage? This 12-13mpg is a fricken joke for a brand new truck. If I can't find a way to at least get 17-18mpg, this thing is getting traded back in.

So far results are 2-3mpg improvement over stock fuel mileage. We should be getting more results here shortly.
