This boost controller was designed from the beginning to be easily installed and even easier to use. It plugs into a sensor and uses the factory DME to re-map boost, timing, and fuel maps. Changes can be made via Bluetooth, allowing you to use your smartphone to turn boost up for max performance or down for conservative driving. The app contains a live boost monitor that streams data in real time.
