If I'm running 16-18 psi boost under hard acceleration, what size turbo do I likely have? And, potential h.p. output? Or, do you need more information? I don't want to have to take the turbo off or other parts to check for additional numbers, etc. if I don't have to. And considering the cost, I don't plan on upgrading the turbo anytime soon. If it helps, I have a BPM TMIC and a BPM GT Exhaust. And, the car is an '02 WRX.
