sc kansas | I have a 99 with super chip +90hp, +50hp injectors, +50hp i pump, fass fuel pump, jack brake, air ride controlled from cab. It runs WELL. Put a presure gauge on the post and watch it. I have had trouble with i pumps before on this truck. Pulls 36 foot fifth wheel. Not much goes around it. Still get 11mpg pulling hard at 70 mph plus. Get 22 no load. 4x4 extended cab. It is definately worth it, you wont know the truck and the power.
