cold idle
Ok, I recently did more work to my ride. I did the whole forged rotating assembly as well as added a FAST 92/92 combo. Well, now, the car will not hold a cold idle. I replaced the IAC motor and still nothing. It will go dead if you let off the pedal. Once it warms up, I can hear a huge vacuum take over and the car then idles on its own. What do you guys think?

I just replaced my TB with a S3 polished TB. After i installed it i could hear my intake suck so much air, i thought it was also a vacuum leak. I had to use HPtuners to tune the Idle Airflow and IAC steps for start up since i was sucking so much air. I also installed the LS6 intake after the TB. You might be in the same boat i was in

was the cold start tuned?
or just WOT and/or driveability.
mine has been tuned twice, and even with a part throttle tune, it surges all over the place at cold start. soon as it hits closed loop it smoothes out in seconds and holds steady at ~900rpm
