This is my first turbo honda, first time ive ever been in a turbo car actually is my own.

The car is an 88 Crx si, d16a6 forged motor with a t3/t4 t04E 57 trim. 3" open downpipe and an RFL BOV

Now I know my car is loud, from the open exhaust, loudest Ive heard on the street anyways. But Ive always noticed that my bov wasnt as loud as I thought it should be, it does a little flutter that is very un-audible if I boost a pound or two, but when I floor it and build 7-12psi its really not loud at all

Like I hear some vid's on hear with dsm bovs and there loud, you can hear them in the vids and they dont have to floor it like i do for some noise, srt-4's are loud as ---- with an aftermarket unit, can hear them far away

Now up until a week ago it wouldnt hold 15psi, it would start squeeling and letting pressure out before redline, so i shimmed it with some washers on both sides of the spring, it now holds.

I also dont really even START seeing any boost until about 3800, 15psi by maybe 5200 I really dont know but its up there. I always thougth that was just because of the bg turbo on the small motor. Then Im reading some people seem to get boost maybe even a fair bit quicker.

How do I test it short of buying another BOV?
