What was the ambient temperature for the before and after runs?
ambient temp on the day of the dyno was about 70* and I was seeing about 100* IATs

I also installed the new MPX and the car does feel faster but I can not get any more boost then about 15psi no matter what blower I put on. I had the MPIII then the MPX and now the new MPX and all never made more than 15 pounds and all were at 25% OD. I have tried new belts, MP springs and checked for leaks. D. Dalke do you think the cam thats in my motor is a possible cause?
Have you raised your blower to add tension? Do you have a chart that shows the boost? I'd like to see the actual boost curve.
Other than that, I don't remember your exact cam specs, but I'm guessing we could probably improve on them. Also, if the motor has been raced a lot or over revved a few times the valve springs are probably shot. You'd be surprised what a modern set of valve springs will do for a motor. You can change them without pulling the heads or motor.

Ready for round two whenever you are! Remember the last one? LOL Hell I will whoop you with my 4-banger instead.
After swapping in my MP2S last weekend I took it out today and my boost is up 2 psi to 14 over the 12 psi I was getting with my S-model. I'm going to get it retuned in a couple of weeks so it'll be interesting to see what my new power levels are.
