Ok just to give a little history we have a 2016 SS auto. car we go to the track fairly regularly car has run consistently 12.10 -12.20 in dead summer heat with 1.8 ,60' so we decided to go with the GM CAI , installed and reflashed by GM dealer to retain factory warranty so we go to the track Friday night to run and the car runs 12-90 to 13 flat all night with 2.11 ,60'

Has anyone else got the GM part & reflash with same issue I will be calling dealer Monday but I know as soon as I tell them how I know it's slower (by drag racing / et's) it somehow won't be there issue.

One other thing it could be but not is my wife brought the car in to dealership with 10,000 miles for a vibration /shudder on light acceleration & at steady speed they flushed and drained the transmission 3 times .

So we did both of these two things before going to the track so I don't know which one did it and or how to resolve the issue any suggestions would be appreciated.
