Does your BOV hold Boost?? What are you using?
I have a Baileys Motorsport DV/ Held 25psi during several boost leak tests. I havent tested it much higher than that.
BTW I have a almost brand new WORKS DV. I have never used it or tested it.

I used a Greddy type s, I didnet check for leaks but I can tell you my stock 1g valve went 12.20's and drove great, my crushed 1g went 12.00's and drove not so great, and my Greddy S went low 11.90's and drove pretty good. The Type s had the small spring in it and the screw turned in about 6 turns.
Almost every BOV with an adjusment screw leaks there. That's what they make teflon tape for...
After having half a dozen BOVs tat leaked and had issues, I fashioned a tester out of HW store parts.
Attach the compressor and crank up the pressure...

My MR valve leaked at 19psi. Crushed it held to 21psi.
I bought the APS dual vent. First test, and yes, it hissed at the screw. A little teflon tape and retest.
It held 40psi with no loss for over 5 mins. No complaints here with the APS unit

What spring have you got in your unit!!
i just installed mine and ......
well the partial throttle is terrible, bucks and dives to the point were it is almost like massive surge!
i am gonna try different spring if that don't work!
I am gonna burn it and dance around it.
