2010 Camaro L99 w/cam and magnuson, long story short, this car came to us from another shop and was a complete mess, we have rebuilt the engine, and repaired countless other issues from poor workmanship. The car is now running well and makes very good power. Driveability is also good with the exception of the idle. No matter what I try it seems like the car will not respond to any changes in the idle tuning. It always idles at around 950 rpm. When we received the car the tuning was so far out, and changes had been made in places i have never seen, we have had to dial in so much other stuff I'm just thinking I am missing something obvious, the car doesn't seem to care where I set the idle it just stays at 950rpm all the time. Other than that it runs great, any ideas guys. Thanks
