Vacum is when the engine is pulling in air under its own power. This is cause by the movement of the pistons, with a turbo it forces air into the engine under pressure.
The more vacum you are reading the more efficient you are being on the fuel I think.

Vacuum on the inlet manifold on an N/A car, shopuld be more vacuum at idle/overun. Close to 0 at full throttle.
ie at idle the engine is sucking against a closed throttle plate, so vacuum.
at full throttle it should be as close as possible to 0 so the engine is doing less work trying to suck air in so (more air less losses) more power.
thats presuming it's a car gauge, otherwise you've just got a compound gauge with which you can measure other things such as the efficiency of your hoover should you feel the need
