I've got a '91 turbo and was just wondering if anyone knew how much boost the standard BOV can handle before it will start to leak?

I plan to raise the boost once I finish the exhaust system (1 3/4 " + 2 1/4" twin dump into 3" mandrel bent straight through system) and am unsure if it is neccassary to replace the valve once boost is raised to 12 PSI.
