Car is stalling when I come to as stop, after boost.
I'm running a Hellion single turbo setup and it seems like every time I get on it hard then let off all the way or brake immediately, the car dies. I've been trying to figure it out for awhile now. I have a couple ideas of what it could be. I thought it might be because the IAC, even if it's working properly, can't compensate for such a larger volume of air moving through the intake piping and then it dropping off quickly when I let off the gas pedal. To fix it I thought about making the setscrew on the throttle body stick out a little farther to keep the butterfly open a little bit more at idle, then disconnecting the battery to reset the idling parameters in the ECU, then letting the car sit and run for about 15 minutes to re-learn the idle. I figure that this might take some of the burden off of the IAC to properly idle the car by letting a little more air than normal flow through the throttle body itself. Maybe somebody on here can give me a little bit more of a concrete answer than just my speculation.
