I have a 02 voyager 3,3l. It's supposed to make about 174 hp, but feel's slower than the previous gen producing 158 hp. It also uses more fuel. The main reason for this, is because chrysler pulled more hp from higher rpm, wich make's the engine struggle to produce power in low rpm's. Can anybody tell me if there is any good tuningprograms/chip, or other tuningparts that gives me more power and torque a little earlier in the powerband. I don't want to change the engine to the 3,8l, and use even more fuel.
