No, it doesn't work at all. Boost referrence pressure coming in the top via vacuum port completely offsets boost pressing against the vlave which is at that point being held shut by spring pressure. You close the throttle so the vacuum port sees vacuum while the bottom of the valve sees pressure and it overcomes spring pressure and bypasses air. The other way around it's closed all the time, great way to get compressor surge.

I see what your saying ,Did'nt really think of pressure coming down that line under boost and helping hold the valve shut, guess I'll swap it back, but it does work, you can hear the pressure expel when you shut the throttle.
