yea with 19lb injectors thats still pretty hearshon the motor... The cars are lean to begin with stock and with the super charger its have to be crazy lean. You can try taking the valve covers off and re torquing the rockers. That could help ya. Run a hugher grade of fuel 93 or 94.. also a good thing to check, pull out a Spark Plug and see what it looks like.. If its white and depositless, then your way to lean and its contributing to you knock.. let me know..
