If you need to run more than 1 bar of boost, you need a manifold air pressure sensor with more range. Our 3-bar map sensor allows you to run up to 29 PSI of boost. This is a genuine GM sensor.

Beware of ‘imported’ units sold as genuine. These are notorious for two problems: The ‘zero’ manifold vacuum setting being different unit to unit. Also, the linear output drifts over time. (See the image for detecting counterfeit sensors)

Don't forget to pair this with our brand new and stylin' MAP sensor bracket
