Check your vacuum source and make sure the piston on your forge is lubed and clean if you bought it used. Is yours and auto by chance?

Yep looks right, I have the same unit. I found my vacuum line was cracked once that was fixed it worked well. Just make sure your in boost hard then lift, I know mine is not really loud at light throttle or low boost like some of the import cars you hear around town, if that makes sense.

Is the BOV's piston adjustable? If so, it could be adjusted too tightly for your setup and not expelling your boost. Be careful! If it's not opening the pressure isn't leaving and your turbo/Motor will pay dearly. Then you will too to fix it.

You could also remove the recirculator hose and plug off the intake hose. What you have done serves the purpose but not having that hose looks better

Do you have a list of your mods somewhere? For example, is that your ECU next to the battery? What are those things that look like injectors near the oil filler cap? What's the black cylindrical object where the brake booster would be on a LHD car?

Very cool

Try using a different spring if the interchangeable ones were included. If you take it apart you might find the source of the problem if its related to the BOV. Everything looks right from what i can see though. Good luck
