here's the link from the engine section. Not one person wants to offer any kind of help or insight. Someone must have put a ls2 TB onto their car, and had an issue, but from the responses, you would think I am asking a moon mission question, lol. anyway, i figured my nitrous buddies might be able and willing to help, as they know the effort I put into helping others.
