I read the thread in its entirety a couple years ago. Looking at the very first picture in this thread shows no connection to the turbo inlet.

Since you know the above, 100% WGDC should be FULL MBC control (closes off EBCS forcing pressure through MBC ONLY). With the EBCS going to the inlet, you cannot have FULL MBC control as your boost pressure will find its way into the inlet vs pushing the ball and spring.

In the path of least resistance, you don't want one of them to be a vacuum source. Might as well just stick with an EBCS only setup. Either restrict the pressure via the EBCS or the MBC. The boost will find the easier route.

Tuning is not a problem; I've done a car or two.
