    Gas economy tune 03 Silverado 5.3?

    Anyone have a good one? I'm more interested in gas savings than power right now. It drinks the gas(no I'm not a lead foot). All scans look fine. My TA got better mileage than this when it definitly shouldn't have with the things that were done to it, and the way I drove it.

    If you do, before and after if you checked.

    what kind of mileage are u getting now? i have a 06 5.3 that i have been playing with... my f body gets better as well which is not uncommon seeing that the truck is alot heavier and not aerodynamic..
