Reading a Boost/Vacuum gauge?

This is probably a stupid question, but:

If a vacuum/boost gauge is hooked up to the throttle body below the butterfly, it will show a vacuum at idle. Let's assume, just to keep the math easy, that it shows a 1 bar vacuum at idle. Let's also assume that the turbo system is set up to produce a maximum 1 bar of boost.

What will the vacuum/boost gauge read at maximum boost? 0? Are there other variables at work that would affect the reading?
