Hi,

First post with a question. Trying to dial in an idle tune on a 403 ls2 build with afr 205 heads, Fast intake, N/W 90mm throttle body, 232/232 on 114 lsa cam, a4 in an 04 gto. IAC is off STIT is off and I'm new to this. It's also running very rich at idle. It was dialed in at 592hp/550t on Westech's engine dyno earlier this year.

Thanks.
