As many of you know, me and my friend done a head swap on his 96 LT1 Camaro. Also, he had the computer re-done and now the car won't shift....well, he sent the computer back and is supposed to get it back in a few days. While I had a scanner on the car we noticed the TPS voltage was only .057. It's supposed to be .067.....this car has a 58mm Holley throttle body on it that you can adjust the throttle blades with the adjustment screw. My question is will cracking the plates a little more increase the TPS voltage or do you have to modify it in some way?
