Big problem with my power dyno numbers

[mazspeed]

Ok, I went to the dyno tuning session today and here is my problem, and here are my numbers. At the wheels I got 350ft pounds and 340hp. I spent 20k on Frank's advice on this supercharger setup and at 9 pounds of boost I gained 0 horsepower over what a stock zz430 would make. This too me is VERY unacceptable. The numbers as far as timing and air to fuel is perfect now, but these numbers are not nearly what they should be. I drove the car today, and it didn’t really feel any faster then my straight zz430 setup. What the hell do you guys think the problem might be? Can you tell I'm pissed?
