Under wide open throttle the car is starting to break uparound 10 psi but it doesnt do it all the time. Mods are
780cc inj
sc61....20psi
z32 MAF
Greddy Intake
Step colder NGK brand new Iridums
Enthalpy tune w/ safc2(just to tweak it alittle also for RPM display)
Intercoller piping is all 3in.

It just started to do this, never had any issues before on 20psi, the z32 is running open with no filter just a screen. Does anyone have any ideas?

Thanks
