Factory turbo boost

Just a quick one:

Have we reached a concensus on what boost levels is the WRX running in factory trim? Can anybody enlighten me on the observed boost in all the range of RPMs? Where did you find peak boost?

Thanks,

Actually a stock WRX at sea level runs only about 13psi or so. Open up the exhaust system and you'll have about 14-14.5 with an occasional spike to 15psi.

Boost in lower gears will not get as high and boost also tapers off as you reach redline.

Fuel cut is around 17psi but your already past the efficiency of the stock turbo anyways.
