With my old Magnuson kit(MP112) car doesn't make any boost unless I bring it up over 2000rpm. Also I like the internal blow off valve and I'm happy my car doesn't whistle. Nobody even knows I have a supercharger until I let it rip. This is my numbers with stock cams and exhaust manifolds with factory cats.
Way too much to list. I'm broke because of it. Tuned by Blue Collar Performance.
