stock boost gauge

how accurate is the stock boost gauge on 02 wrx? is it a real boost gauge or is it just for show? 3000gt vr4 has one, but it is not a real one and work with maf sensor only. also is stock bov good for 15-16 psi. we have a stock 02 wrx and we are thinking to up the boost to about 1 bar, but not sure i can trust the stock boost gauge. the car also has catback and cold air intake on it.

It is accurate the only thing is it's not written in pounds or bar....look closely at the gauge. I now use the one on my Cobb AP V2 and thats what i go by.
