A stock wrx (stock turbo'd) can reach much higher than. How effecient that is is based on the fuel and mods and tune of course. I ran my stage 2 setup to around 20 PSI for some time.
When mine was stock I was right about 13.5. Stage one put me at 14.8(ish) stage two 15.8 in the summer. 16.3 in the winter.
