Pretty sure 7psi standard, you can't "tune" the standard ecu, you can wind up the boost if you have a after market intercooler + exhaust etc. You don't wanna go anything more than 1 bar.
Look up on the dyno result thread
The GTRS kit simply WON'T give you 300rwk even with pon cams.
My best bet is GT3076.
Ps i have my GT3076 external gated for sale, let me know if you are interested
