RAFIG and IDLE tuning with TVS1900.

Heya Folks,

Very new to tuning and this is my first real undertaking of tuning myself so any advice is welcomed and appreciated.

Iv been attempting to idle tune my 6.0L (24x reluctor, LS1B PCM with COS3 3 bar SD tune, STFT working and enabled) with LSA TVS1900 blower. It has a 92mm DBC throttle with a Holley IAC, the throttle has a 6mm hole in the throttle plate.

I have followed the idle tips and tricks tutorial and performed RAFIG numerous times. My desired airflow figures are now in the 20 grams/sec range which I believe is excessive. I still cannot get the engine to stop stalling after even a small rev or even a big rev. The car is a conversion with a non GM auto transmission but the ECU thinks that the car is in gear 24/7.

Update, turns out IAC effective area has to be close for anything to work. Cheers



TIA!
