I have an 03 Chevy 2500HD. I'm looking for more low end power without getting crazy or totally killing fuel mileage. I have a 10,000 lb camper i pull thru the big hills in Pa.
You could try a computer reprogrammer like a Jet, Hypertech , Diablo ones like that or you could lower your rear end ratio, but that will start really killing mileage.
Thought about it. Gears are already too high. About 2350 at 65mph. Thought about an adjustable programmer but never had one.
