Need help! My '14 CTS 3.6 is in limp mode & trans safe mode since installing the TB. I don't know where to go from here, and trying to get a response from Will at Overkill is impossible! Extremely disappointed, but glad I didn't buy their supercharger, cause customer svc is the worst I've ever experienced. I just purchased the car and have been so happy with it, and excited to do mods and Overkill has completely ruined it for me!
