Default Re: Holly HP EFI-- Idle & IAC Tuning

Just like Jeff said, we completely disabled the IAC and left it unplugged, had the same issue with the same 5.0 stock combo, we were using an Accel DFI system back then, shouldn't matter though, we turned the idle screw up on the throttle body and took care of it, idled a little high but we didn't mind.
