Ok. I know the TopGun chip is set to run at 11psi. I also know that a few members here are running 12psi. I also know that at 14-15psi, the turbo is starting to choke. Is it safe to run 12psi on a stock motor? How much more power does 12psi make over 11psi?
And for those of you that are running 12psi, are you doing it with an EBC or MBC???
I've been running 12psi for quite some time. I did it on stock internals for 20k miles without issues. Teh only reason I rebuilt was because I REALLY overbooted it(boost control went bad) and caused a hole in the piston.
