I got a 02 voyager 3,3l producing 174 hp. It feels slower than lll gen grand voyager with 158 hp, and uses more fuel. Does it exist any good tuningparts/ chip for the 3,3l that will help. The main reason i guess, why it feels slower and uses more fuel, is because chrysler squeesed the new power out higher in the rew range. I want more low end torque. What to do? I don't want to change engine to the 3,8l and use even more fuel
