I decided against this btw.

Spent a few hours reading through the forums, the gain seems to be realistically 1.5-1.7 mpg. People claim 2, 3, or 4 mpg improvement, but if you look at the posts with actual data, including decimal calculations, its always less than 2 mpg, even with the dpf delete.

At the rate, it would take 4 years to break even. Plus the added toque Im sure comes with a turbo, fuel pump, trans wear price. And I dont really care about making my 4800lb Jeep fast.

So Im thinking about investing into a taller gear set. Everyone who owns these complains about the high freeway rpm, but no one has done anything economical to solve it, to my knowledge.
