I have seen so many threads about this now, my 2cents you cant run more then 10psi stock as the ecu will cut you, thats my understanding. So if you have a remapped 32 ecu, PFC, piggy back or what ever, and the other supporting mods fmic, exust, induction I cant see why you cant run 12 to 14 all day every day on a safe tune, what i mean by that is a rich tune not leaning out or timing not to advanced.
I run my r33 gtst with remapped ecu by NERVE fmic, HKS pos, apexi exst at .7bar and .9 when i want to race and always on BP Ult fuel, and the last Dyno day on a dyno dynamics dyno I reached 216rwkw ask any of the ACT SAU crowd and that was on .7bar or close to maybe about .75 close to 8 before you all jump up and down saying bull shit, I am unaware of any other mods, but sure its only a stock turbo as it was off recently.
Oh last thing Dynos are for tuning not real power out put
