Boost Controllers

The boost controller sits between your turbocharger and wastegate, where it modifies the pressure signal for more consistent performance. When the air pressure leaving the turbo exceeds the preload of the spring inside the wastegate, the wastegate opens a valve allowing some exhaust gases to bypass the turbo, reducing boost to safe levels.

However, the wastegate can partially open before its rated psi, resulting in inconsistent boost response. A boost controller prevents the wastegate from opening prematurely by regulating the boost signal. We carry manual and electronic boost controllers.
