boost gauge is a pressure gauge that indicates manifold air pressure or turbocharger or supercharger boost pressure in an internal combustion engine. They are usually mounted on the dashboard, on the driver's side pillar, or in a radio slot.
Quite frequently there's a power band inside a given range of available boost pressure and it's an help to performance driving to be conscious of when that power band is being approached, in the same way a driver wants to be conscious of engine revs per minute.
A lift gauge is used to guarantee unnecessary pressure isn't being generated when boost pressure is being altered to levels higher than OEM standard on a production turbocharged automobile.
Easy methods can be employed to extend factory boost levels,eg bleeding air off the wastegate diaphragm to 'fool' it into staying closed longer, or installing a lift controller.
