IAC position vs Desired IAC count My actual IAC count is 0 when the car idles and my desired IAC count is 136-138. What dose this mean?
I have a 90mm FAST set up and I've been told by a few that I may have to drill a hole in the blade and back the stop screw all the way out to get the IAC counts to around 35 but the thing that confuses me is when the actual IAC count is "0" doesn't that mean it's already getting to much bypassed air and 0 is the 100% closed IAC position? If that is the case how would drilling a hole in the blade and allowing more bypassed air threw going to help?

Ok you guys got me thinkins so I went and did a quick test by putting my IAC in my friends 99 ls1 and it worked fine in his car so it's not an IAC problem it's either the tb is letting to much air by or one of the flow rate tables is off in my edit file.
