are you going by the stock gauge or by an aftermarket gauge. if your going by the stock one. thats not very realiable. does the car still feel like its pulling at 11lbs or does actualy feel like its only at 8 or 9.

BTW.- did you really HAVE to pass the car haha..

well if the car still pulls that hard like its got the full boost maybe your gauge is a little off or possibly maybe the wiring has a short. check all your wiring and lines for the gauge. otherwise it dont really sound like a mechanical issue of the supercharger or anything..

but im not 100% sure. try giving BNAYLOR a private message. you can pretty much go to any other post and find him on one of those he posts an answer on almost all. hes really good and the one i recommend.
