Boost controller Question? WRX

Ok I installed my Stage 2 boost controller last night. My question is what is the max boost I can turn it up to without blowing my motor.

Mods that are done so far.

Down pipe.
Exhaust.
Aps cold air intake
Bov
Ground system
B&m short shifter

I currently have the stage 1 set at stock boost.
The stage 2 is set at .1 Mpa which I believe is like 14.5 psi.. Is this to much?

14.5 is fine. But it is still possible to damage your motor. I'm running 15.5 without problems, and I know there are alot of people running higher. Just depends on how you treat your car.

No engine management? Your MBC is going to cause partial throttle boost issues your stock ECU won't be able to handle. Not enough fueling resulting in high EGT's and possible knock.

Nice screen name.
