i recently put a 355 in my camaro, the motor was in one of my other cars and ran like a rapped ape, so i put it in my camaro. now it doesn't seem to have any power. is the computer chip, holding the spark and fuel curves down, the chip is from a 305 carb.

What does a "rapped ape" run like anyway ?

Wanna give us more details about this car ? Induction system, heads, cam, intake, Q-Jet still on it ? Etc etc
