: If you have a wastegate (which you really should), it is possible that it loosened up and is set to relieve the pressure at a lower boost level. If there is no pressure protection on your system, then you hoses are in bad shape.

: Bassem

Bassem, how many supercharger kits do you know of that employ a wastegate?! Certainly none for the M3. A wastegate is required by a turbocharger because without one, the turbo will generate up to 60 psi in some cases! In a supercharger kit, the boost is controlled by one thing: the size of the pulley. That's it. Therefore, none of those fancy electronics which are common with turbos to control boost are appropriate. A supercharger's boost is Mechanically controlled, not Electronically controlled. Therefore, no wastegate!
