Stock TB?? I replaced my IAC and IAT with my TB cause the BBK 52mm made my car idle like crap. My A/F bounces lean like that at idle still.

Hmm, mine didnt have that issue when it was blown. It could be reversion from the blower?

Yeah i use proscan. I can send it to you and you can open it up in note pad. I dont have my lap top at work but I will log it tonight just at idle and send it to you.
