Yep, i've been thinking along those lines also..Either that, or a solenoid valve that can let extra air into the the motor for a fast idle. A perfect place to ingest this air is the EVAP line, right on top of the TB. I took that line off while idling, and it raised rpm to like 1400, so that is plenty of air to fast idle with. Only problem is finding a valve that flows enough air. I've already tried using the EVAP solenoid, but it wont flow enough air..
Either way, we are going to have to remove and plug the stock IAC air bypass port, because at least on my car, the pintle gets pushed in when going into boost, and comimg back to an idle, the rpm is much greater. Not a big deal to fix though..
I've already drilled out the TB stop adjustment screw cover- its only a thin metal cap over it- and that reveals the torx head throttle stop bolt. I just turned that bolt in to raise the idle, then unplugged the IAC. But the higher idle after boost problem is still there, and cold start you have to keep your foot on the gas.
