Also I'm thinking of getting a fuel return system on the car. What do you guys think. It's troublesome but I'm not sure if I can get away without one.

Thanks.

Hi guys. Final numbers are out.

471whp on mainline Dyno
HP gain is about 50whp throughout from 5k rpm to 7.5k rpm. Below that is about 20 to 30whp.
14psi of boost at 7500rpm
IAT at peak is 54 DegC
DW 1000cc injectors at 85% duty cycle at peak
No fuel return.......YET........
Fuel pressure at peak is 40PSI. Too low in my books

Cheers guys.
