ok first off mods are intake, downpipe, exhaust.....thats it. still in sequential setup. it just started doing it recently, but around 3k rpms when the first turbo should be boosting, it would go into parallel mode(i think). the boost would start dropping and then the exhaust/engine would get louder(like in TTC mode). if i rev it once or twice it would go back to normal sequential.........any suggestions?
