boost+gauge

A **boost gauge** is a gauge that indicates the amount of boost pressure present in the intake manifold. Many also measure the vacuum level in the intake manifold.

On Z32s


Factory Twin Turbo models had a boost gauge integrated into the speedometer, mirroring the oil pressure gauge under the tachometer. While helpful, the stock boost gauge is considered fairly inaccurate, and those raising the boost pressure on their Zs are highly encouraged to buy a high-quality aftermarket boost gauge to prevent setting the boost level too high.
