LS2 TB IAC not working
I have a 01 C5 With a 402, LS2 TB and a Adapter Harness. My IAC is not moving from 149 where it is set. I put a stock GTO TB on it and it still didnt move. Is there a chance that the wires on the adapter harness are pinned incorrectly?

Are you tuning, or tuned using LS1edit, EFIlive or HPTuners?

I read that I am sopposed to take the 2 wires that dont get used and tie them in with 2 wires that do get used?
