id say 22 psi on stock injectors is the max
new injectors u can boost as high as your setup allows u
i think the stock turbo runs out of efficency at like 25 psi

The EVO on 92-94 octane fuel seems to handle 19-20 psi with no problems at all clear to redline.
Regardless of the injector size and turbo size (basically) the limiting factor of running more boost is fuel octane. A more efficient turbo will let you sneak by with more as the air stays cooler for the same given boost level not to mention the exhaust getting out of the combustion chamber quicker through a bigger turbine. In the end you are still going to be limited by the fuel you run more than anything else.
With the BR475 on our EVO and the AEM w/1,000 cc injectors we still could only run about 21 psi on 94 octane. Good enough for a very quick spooling 401 whp though.
