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.

Get a fuel return system quick before something bad happens.

Those numbers are very very low ..even without the fuel return ..40psi with 1000cc injectors is still a lot of flow for 14lbs of boost ......I was at 522whp at 12.5 lbs with 93 oct fuel with the stage 2 kit with 650cc ...I was planning to add the methanol kit and would have been around 575whp ish ....what fuel are you running ...91oct?....93oct?.... or e85 ?
