Ok I have a 94 sc has a 10 % pulley on it.. it has had 12 - 15 boost until recently .. it wont go over 5 boost.. the super charger sounds fine.. No found leaks in system... also it only has maybe 5 psi vac at idle.. I checked the bypass valve and it seems to operate properly .. Oil in the supercharger is good.. I did however find that the bolt was missing from the tps.. would this have been causing the problem .. even though it did NOT set any codes..? if not I am not sure where else to look
