Yah, 7 psi on that puppy should be quite a bit more than 202 WHP. =/

External Tial wastegate 38mm I think
Cool Mist Water Injection
Greddy Ultimate
3" exhaust but stock J-pipe
Fidanza Flywheel
JWT S3M Cams

Car made 330HP @18psi but the night before it was holding 21psi comfortable on the road tune. What would cause the car to not get the 21 psi on the dyno runs? Is this power good for his setup? I am wondering if the j-pipe is holding back some power being stock and whereabouts can I locate a 3" setup and retain the A/C compressor. He is using the stock GTiR manifold and has an external wastegate welded onto it. Also he just tack welded the flapper on the back of the turbo shut, wondering if on higher boost it is leaking. Let me know your opinions.

What timing are you guys running on top? what fuel?
I think you are down in power aprox 50-70whp.
