Need some help dipping into the 11's
Ours is 3750 without driver with a BB and fiberglass hood and bumper. Not a lot else done to lighten it, no inner fenders and no heater....
I agree with keeping the double pumper. It just needs some tuning.... Also remember these suckers push a lot of air so your MPH are usually a couple MPH slower then what your combo would have in a car.
DON'T let anyone tell you a truck cant hook up on a small tire!
