I got with Allen this weekend to see if we could fix my idle surge, and the only thing we all could come up with is that the Z06 MAF meters alot more air than the stock MAF at idle. This causes IAC to zero out and then causes the idle to surge when you turn on the a/c or go from drive to reverse. I hope I got that all right!

So what we did was program for the cam and the stock truck style MAF and trick the IAC into thinking it was at zero by opening it up with a IAC "tester". Not sure what it was called! So I will be putting back in the stock truck MAF and need someone to reset or explain how to reset the IAC to zero with the truck completely cold.
If any body knows anything about this please chim in! All help would be greatly appreciated.

Thanks,
Steven
