Regardless of MAX of the gauge or the app the max boost allowed will be governed by the cars MAP Sensor.

Perhaps this will be easier to understand.

Bosch MAP Sensor minimum is 0 bar and its maximum is 3 bar. So as far as the Bosch MAP Sensor is concerned:

0 bar = A vacuum
1 bar = Normal atmospheric pressure, the air around us(0 boost on a gauge or app)
2 bar = 1 bar of turbo boost pressure(1 on a gauge or app)
3 bar = 2 bar of turbo boost pressure(2 on a gauge or app)

The values when driving change constantly between the max and min of the MAP Sensor. Foot to the floor boards under heavy load you would expect to see close to the max of the MAP Sensor, 3 bar(2 bar of turbo boost on a gauge or app).

Hope that helps ..

EDIT.
Are you asking because you plan to buy a gauge or app and need to know what range is appropriate to buy the correct one?
