i have a tune that increased my mileage from 13-17mpg to 18-22mpg, its a nice clean tune with a 65rwhp increase

this guys is selling EFI live without the EFI live, which is fine, but then you're stuck with what hes selling you

But Im still telling you that the 2011's are giving guys a lot of grief, you have a truck that gets better mileage with a dpf, urea, and a ninth injector than trucks that are a year or two older

The new 2011 engine is an LML not an LMM. There's more differences then just the tune.
