05 STI PPP stock boost

Can anyone tell how much boost does a stock 05 STI with PPP make? And also compared to the boost of the stock 265 ps?
thanks

This thread shows BHP / torque differences from standard to PPP in post #4 but I don't know the actual amount of boost, probably around 1.5 bar (21 psi) with PPP perhaps.

Thanks

The mechanic who just installed the ppp on my car told me the car is now running 1.4 bar measured, I guess that is right then.

In stock form what is the max boost pressure?
