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.

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.
Manual (or mechanical) boost controllers consist of another spring-actuated valve that allows some boost pressure to bleed off or bypass the wastegate. They usually have a knob that allows you adjust the responsiveness. They’re simple, inexpensive, and provide maximum spool-up speed.
Electronic boost controllers are more sophisticated, using solenoids or stepper motors to limit the activation of the wastegate based on a variety of inputs, including manifold pressure, rpm, and throttle position. These controllers help address control and drivability issues, and provide overall better performance.
