Yes that's normal. Ignore the requested values at idle as the MAP sensor is in the boost pipe, so does not read vacuum.
As for what the readings should be, depends if it's standard or not, or if it's an Edition 30 or GTI.
Whatever the readings are in boost, deduct 1000mbar. If you see an actual of say, 2250mbar, the real boost pressure is 1250mbar, or 1.25 bar.
