Hey, Thanks to both of you. I will find a tuner here in vegas to take my car to. Timing is 38 drgrees and I will check the jets sizes, idle mixture screws are out 1 turn on all corners. That is all I know at this point. thanks again guys. I am learning. But will take it to the pros. Scott did a great thing by fixing my motor. He only tunes on the dyno and not when the motor is in the car. Besides, I think he is more the engine builder than a tuner of customers cars. Which is probably less of a headache, lol So if anyone knows a good tuner of supercharged motors in Las Vegas I sure would appreciate it.
