Rough Start

[KANE]

Mine did the same when I first installed the Supercharger....in my case it was some air in the fuel rail....I just turned the key and released the pressure from the fuel rail, I started it up and pressed and held it for about 5 seconds...be careful not to do this on a hot engine as releasing gas could hit the manifold/or header and cause a fire. BTW - release the fuel into a rag...this wont allow the fuel to spill.

Hope it helps - good luck!
