Procharged C7 Idle issue
Hey guys, just got my car back from the final dyno and the idle sometimes bounces between 700 to 1000. Basically idling up and then right back down. I will try to get a video in the next couple of days. It doesn't always do it but something that I noticed that was different than when I was breaking in the motor and clutch for the 1st 500 miles. I know the car had a basic tune for the break in and the dyno tune is more in depth but I wouldn't think the idle should really move all that much when out of gear and the clutch disengaged. Maybe a tuner on here can help me figure this out so I don't have to drive another 2.5 hours back to the shop to get it re tuned. Thanks guys!

My procharged LT1 A8 sits at 650 rpm in or out of gear and does not move at all ... I hate to say it but you need to talk to your tuner as that should not be happening....
Do you have HP Tuners , how about an AFM guage and a Vacuum/Boost Gauge ?
