Getting the DPF off the truck helps a lot. Stacks aren't going to do anything. 35" AT's on the highway will be alright, but around town it will hurt you. A lift isn't going to help because of added drag and weight.how will my mpg' be with a dpf delete, 7" dual stacks and tires and lift?
Fuel mileage will suffer. The look will be great.how will it do with a 4-6" lift with 35-37's
We don't offer a 340 tune....what needs to be done to my tranny to run the 350 or 340 tune?
Mileage is going to come with a conservative right foot. You can do other things to get your truck more efficient for better fuel mileage, but doing a lift and larger tires ain't on that list. A stock height truck with 3.55 gears, a DPF delete, higher horsepower tune (250, 275, 300), and an intake could definitely pull off some good fuel mileage.what are some things i can do to get better mileage, and how much would it cost to do head studs, and a torque converter and rebuilding the internals
