I know my GTI has a vacuum generator to boost the brakes to counter act the turbo.

Not sure. If the vacuum lines are plumbed after the TB, then even on a boosted application, the manifold sees high vacuum since the TB is closed and the engine is still trying to suck in air. But that's just a guess. Assuming that the setup is standard: turbo -> throttle body -> intake manifold.
