    2500hd 6.0 turbo gas milage???

    My brother is about to pick up a exsb 4x4 2500 hd 6.0 06-07 classic. I know they dont get for MPG stock but I was wondering what It might do with a turbo mpg wise. The truck will have the torsion bars cranked on 35s with full bolt on's asap.

    It will need a body lift to keep the 35s from rubbing(at least mine did) On the mpg side i got 11 or 12 mpg no matter if i was pulling a trailer empty hwy or city. But it would pull a house down. Does the truck have 3.73 or 4.10 gears? Mine was 4.10.

    410s. Did your truck have stock wheels or after market?

    Im curious about the mpg too. I have 35's and 4.10's in mine, and before i got it tuned i never really got more than 12, no matter what. After the tune, i see about 12-13 in town, and 13-14 on the highway. Am curious how a turbo would help that though...
