It's mostly the IAC...For now, i've taken out my IAC, and tapped the pintle hole in the TB for a bolt, and used a washer on the bolt to seal up the hole where the IAC bolts on the TB. So basically, both holes are sealed with one bolt. The only major downfall to doing this is you have to keep your foot on the gas for a little bit as the motor warms up..after that it's fine. You just cant simply unplug the IAC, because boost will push in on the IAC pintle, and cause a high idle..
