Mine's barely* open at idle, I can never get it to inhale. I don't know for sure what it does at part throttle with boost in the IC pipes.
It might be a problem if I weren't running a speed/density system. All that metered air leaving would cause problems otherwise.
(By "barely" I guess I mean enough to be VTA. Maybe it's recircing the whole time. Guess I should take a look at that, esp since I've been building boost slow the past few days. It was a sudden, noticeable change)

It was the ebay GFB, the silver one posted above, that was absolute crap. it wouldnt seal at idle, no biggie. In boost, you dealt with horrible flutter, or you loosened it and it leaked in boost.
the knock off Type -S seemed to work just fine, but the note was odd compared to my real one. That was later replaced for a genuine type-s as a local deal came available, that was too good to pass up.
