They are usually 14psi my 95 gst was before i started playing with it and modding. They can very though. Have you done any mods, also do a boost leak test that may be the problem.

Stock boost on a 2g with the BCS and T-25 is around 12 psi. Feel free to raise it to no more than 15 psi on he stock fuel system.

It's always good to perform a boost leak test if you have doubts.

when i had my t25 it was a consistent 10 psi. I even had the BCS removed still 10 psi. put on a fmic 10 psi. I had no boost leaks. Get a mbc and crank it to 18 psi because it doesnt make poer after that. I think i read somewhere its like 10 horsepower for every psi of boost on the t25 past stock

installing a fmic on a t25 isn't really going to make much of a difference, the stock smic is sufficient. On the stock t25, internals, fuel system, etc, I wouldnt run any more than 16psi to be safe. Also, I've heard it kind of varies, but stock boost should be somewhere between 13-14psi. Check for those leaks!!

i thought it was 12-13 PSI ah well every car is different hey you can always disable the boost solenoid and gain that extra pound haha
