If you get it going and it has this problem, get a hold of me and I can lend you a TAC to see if it remedies it since you're close.

So I powered up my truck last night to check wiring and noticed that I am having the same problem. My TAC came from the same donor as the engine and ECM. Its #12573059. I bought the GM truck pedal #15264643 that is for the same year Silverado 2500. I am getting full throttle when the pedal is half way down. When I look up the TAC module for a 2003 Silverado 2500 it is showing #12588923.
Were you able to figure out if it was in fact the TAC module causing the problem?
Thanks!
