supercharger problems
 

I just bought a 92 mustang gt. It has a 303 cam, ported heads, full exhaust, a trickflow intake, and a recently added paxton novi 1000 supercharger. It ran fine before the supercharger now it surges when its idling then eventually stalls. Anybody have an idea what the deal is?

did you have it dyno tuned? Not too familiar with s/c stuff. If you, have had it tuned i would talk to the people who tuned it before i started changing stuff. My car stopped doing that when i calibrated the tps (throttle position sensor). Should be .98v at idle. other things come into play though, timing, fuel pressure etc. I would try calibrating the tps and if that doesn't help you can get an Idle control Valve delete deal. Its basically a plate that has a hole in it that is bolted to the intake where the idle control valve is. I have heard that they work well, but tend to leave idle speed a little high (at least 1000)
If you haven't had it tuned that would be priority #1 if i were you just because its supercharged.
