Hey so I sold the lbz and got a 08 lmm mods that I can tell are lift pump,def delete 4” exhaust, and a dmax store Idaho rob autocal trucks 6” rcd lift on 35s getting 15mpg or 380 miles to a tank cruising I’m not sure the time is flashed because I bought it this way has a dsp5 and the autocal does this seem right?. My lb7 was getting like 25mpg tuned and compounded

15's about where i am getting though i dont do much highway. I am leveled on 35's though, no lift. You're doing way better than my tuned 08 6.0 gasser haha. that thing was lucky to see 11-12. You'd think they'd put a bigger tank in those!

With the bigger tires and lift your mileage is about right, regardless of the tune.
