brake booster Y- piece removal

[sambb]

Just wondering if anyone has removed the Y-piece that runs off the inlet manifold that has the air intake and brake booster running through it? From what I can gather a similar system was used on our motor in the B5 A4 audis. There it used the flow of the PCV system through a venturi in the Y-piece to help scavenge the vacuum assist for the brake booster - theoretically increasing the vacuum. Ours seems to take air through a one way valve from the intake and use the flow of that air through the y-piece venturi to assist the flow of vacuum for the booster.
Has anyone removed this feed from the intake and the y piece and just run the booster direct to the manifold? Any noticeable affects on the brake boosting?? They didn't seem to think so on the other cars I read about but there system was a little different.

thanks
