What kind of mpg do you guys get with a 4x4 lb7. only mod i have at all is ppe programmer on level 2 (90 hp). Stock i only got 13-14mpg... now i get 15-16 if i drive 60-65mph. Is this average? I also have 20in. wheels with 33" mud grapplers
I get somewhere around 15 driving in town, and 18 or so on the highway. LB7s in general seem to get the best mileage at or below 2000rpm.
