First post on here - I've been lurking for a while now. Unfortunately, the admins have opted to not allow searches for three characters and my question doesn't seem to be too far out, so here goes. I've installed several GM TBI 7747 systems on my various Jeeps. All AMC V8's. They all run good and I've tuned them to get decent power/mpg's. I'm setup with a Moates autprom/winaldl/etc.

What are some good values (in tuner pro) to start messing with to silence the IAC? All of my rigs have that IAC 'hiss' when hit the throttle. More pronounced when cold, but always has that hiss. Sometimes I can hear it at idle.

Thanks and GREAT site!
