I am tuning a 2008 C6 LS3 A6 w/ G6X3 cam, LT Headers, CAI, and 2800 Stall. The car starts and idles cold fine. Once it is warmed up, if it is idling for a min or two it will start to surge a lot. It will sometimes get so bad that the car cannot correct and will stall unless you give pedal assistance. I noticed that the spark was jumping all over the place when it was surging. I don't have a good long idle log, but do have a scan I did while out driving. The spark is doing the same thing on decel/light cruise, but worse than idle. Any help would be appreciated.
I dont have the WB hooked up on the scanner.
I am running 2.23 Beta
