There is all kinds of info at Scott's site, http://www.sjmautotechnik.com/
I haven't studied it, but I believe the WGFV controls boost by bleeding off
pressure from the waste gate control. Pinch the hose=> no bleeding=> max
boost. Remove hose=> no pressure => no boost (or minimal boost). This is
what I remember from previous discussions. I could be wrong, but I'm sure
SJM's site will explain it in detail.
