I have a 00 WS6 M6 with a procharger. I put 47# injectors and a racetronix fuel pump. I setup the flow rate of the injectors and I'm running COS5. If I touch the throttle it will go up to 2k rpm and hang there for 3-4 seconds. I logged the desired idle flow and it averaged out at 0. I also logged snapping the throttle. I hope someone can help. Thank You

I can't look at these but suspect you have some excess idle air
(maybe now that there is boost at idle?) and then the throttle
follower adds to it every time you open the throttle and decays
too slowly. I'd see whether you need the follower air to be as
much as it currently is (I'd think not) and maybe make the decay
rate higher. With pressure before the blade your IAC just has a
lot more airflow per opening than the PCM understands, so when
it dials up the area computed, you get a bunch more than you
wanted.

Thanks for the advice. I've been playing with the follower and decay but I will play around somemore. I thought someone might look at the tune and see if they saw something else that might cause it. Thanks again.
