I'm also running the PTP WGA T'd off to the green line, black line capped off... not pcm controlled. I was told to do this by NeonDan.
Your problem is right there in your post. The PCM has no correlation between your boost and BOV solenoid. One is PCM controlled while the other is not...
Look closely at the BOV(pink/blue line), it goes thru a solenoid. When you press the gas, the PCM switches the solenoid to route the blue-line into the pink line...therefore sealing the BOV. The blue line is the HIGHEST pressue source in the turbo, thats why its used for the BOV, to ensure its sealed at the slightest boost.
When you get off the gas, it removes this pressue and you hear the pssh...the reason you hear in vacuum is because of your WGA. The WGA is causing the car to hold boost EARLIER than the PCM expects....so pshhh..
