are my wastegates internal?
Yes, the vacuum actuators are out side.

Superdug , the N75 controls the air pressure to the wategates, so it is the "thing" that controls boost.

Yes, you would be loosing pressure with a boost leak, but the turbo can try & make up for it with more boost.

To test that theory, you need to Vag-com log block 115 & see what the requested vs actual boost it.

I'm on AZ also, my thoughts on their knowledge is, most don't have a clue, & just regurgitate what they hear from the people who know.
