Hi,

Quick question. Just put in my boost gauge. Making about 16psi from a 100% stock v4 STI.

I thought the stock was supposed to be 0.8bar (16psi=1.1bar)? Or is that the WRX?

The engine is 100% standard and imaculate so i guess 1.1 is about right?

 

Yes. Std boost level for the v.4 STi is 16psi = 1.1bar.
