i just had my car dyno tuned a NITRO DAVES by Moe. i ran across some Throttle position codes high voltage/malfunction. what could have caused these codes? we speculated that it could have been my new throttle body because of the bump stop mod. i need to get this problem fixed so i can get the car retuned. i have just recently installed tsp 231/237, PP ls6 heads, jantzer TB, ls6 intake. any help would be appreciated.

If your TB goes beyond a certain voltage it will throw a code. The voltages tell the PCM what percentage the TB blade is open. Can you use autotap or something else to scan the voltages? If you are going beyond that max voltage you may need to adjust somehow how far your blade can open.
