What is the average boost level, as there seems to be different versions. I have a WRX 1996 JDM model. when I put my foot down I think it hits about 1.0 PSI initially but then tends to drop back to about 0.6 - 0.8 PSI straight after is that ok or should it stay about the 1.0 PSI or higher. Many thanks for responses in advance.

 

should get just shy of 1 bar if standard and tail off at high revs on that model (same as mine) or a bit higher if any mods. should hit overboost if it goes much higher though

 

Many thanks i do hit 1 bar when picking up then it does tail off as you described. Glad to hear it is normal. many thanks for the reply
