Supercharger PSI levels, whats normal?
Well I just installed a boost gauge finally on my TC. Getting ready to slap the 9.5 pulley on but want to know what is normal for the stock SC setup with boost levels.
I have read 7 PSI is the max boost with the stock pulley but after a day of driving under heavy driving the most I have seen is 5 PSI and MAYBE touching 6 PSI. Under normal driving 2-3.5 rpm I don't see my boost gauge go above 0. I am still learning what is normal when it comes to forced induction and want to know what I am seeing is normal or if I need to fix something before I put the small pulley on.
If I am maybe leaking somewhere, where should I look/test for leaks?
Any info would be appreciated.

^ the setup itself is fine. But we don't know if everything else on the car is fine. BPV sucks, belts might slip for some reason, there might be a leak somewhere etc etc. Switch out your BPV and I guarantee you'll see 7PSI RIGHT at redline as stated above.

I found the problem, my cap on my forge 007 had a small leak, needed a little more tightening. Guess you need to check those even when brand new. I swapped out to the blue spring with one spacer while I was at it. Took my car out and hit 7 PSI at high RPM. Pays having a boost gauge to check that.
