Should I use a Boost/Vacuum Gauge or a Boost-Only Gauge?Updated 3 hours ago

The type of Boost Gauge you need depends on your vehicle and engine type.

Boost/Vacuum Gauges are designed for gasoline-powered engines equipped with a turbocharger or supercharger. These engines typically produce both boost and vacuum, allowing the gauge to monitor both pressure readings.

Boost-Only Gauges are primarily designed for diesel-powered vehicles, which generally do not produce vacuum and typically operate at higher boost pressures than gasoline-powered applications.
