I just got my truck and I'm getting 16 mpg it is completely stock with 225 70 19.5 tires! I don't think the guy recalabrated the computer for tire size. So I'm really just guessing by what the read out says!

Mine is showing 21.8 on the overhead right now which is way off. i just guessing its about 18 in mine. I haven't filled it up completely yet to figure it on paper.

07 2500 5.9 4x4, automatic, diablosport powerpuck, gutted stock intake with K&N filter, 2" leveling kit and i dont kno where that dang silencer ring went. More to come... Exhaust, CFM+, Predator stack, tires and wheels when the money permits

When you get done powerstrokin your duramax only the best is left CUMMINS
