Default

The boost gauge indicates the pressure or vacuum in your intake manifold.
At idle or lift throttle, it will show full vacuum or -70 kPa.
As you put your foot into the throttle and load up the engine, the vacuum will drop (pressure will rise) and the boost will pressurize the intake towards +70 kPa.
It should not normally read 0.
