I am running a 96 GTS-T Type-M RB25DET. Everything is stock. What is the stock boost supposed to be, 10PSI right(.7 BAR)??

My car seems to only be running about 4-5PSI.

Any ideas where to start looking?

I believe it's either 7 or 9 psi. I think 9...

Look for any air leaks first. I'm sure you have already...

It kinda sounds like the BOV is bleeding off. I hear the sucking sound of the intake PLUS as higher pitched noise as well. Just curious for others opinions. I am gonna check everything out tomorrow. I dont really think it is a leak because it would run real rich if it was, right? It seems to run decent enough, just seems a little on the low side.

my is reading at 8psi at stock boost on the boost gauge. All the pipes looks prety tight but i still do hear some air. The bov seems to be in good condition. My rb just run like a eclipse stock turbo only, not powerful enough. Let me know if anyone find anything new.
