High IAC's, how can I lower?
After a TR227/224 and head install. I have gotten my car to idle, but the IAC's are at 130-132 at idle and go up to 152 with the A/C on. How can I get this down to the 50's that I keep hearing to be where I need to be?

Re: High IAC's, how can I lower?
I drilled mines wit a 7/32nd drill bit and hooked up gm's tech 2 and iac counts went as low as 27 and as 2001camaroguy recommended to me should be between 30-40. but as cal said above, as long as ur car idles and runs good dont worry bout them iac counts. As for me ill go 1 more step bigger (15/64) cause my car surges a little @ low rpm's.
