Been having an issue with my 2012 regal GS 6 spd manual. When getting on the throttle hard in any gear,you can hear the turbo spooling up normally but then you can feel/hear the turbo boosting on and off while the car sort of surges @ max boost while still increasing speed. I have no codes, replaced both cam actuators, replaced MAF sensor, inspected for boost leaks/vacuum leaks and cant seem to find any. Been searching for a while and cant find any other threads related to this. Found one but the guys clutch was slipping and was the issue with his. My clutch is good as i know what a slipping clutch feels like. HELP!!!!! I am a mechanic myself and re fuse to take it to the dealer as i dont want to hear the "no fault found" speach haha.
