The Lorenz Racing billet manual boost controller mounts on a 304 stainless steel bracket to the turbo and goes in between the boost source from the turbo and the waste gate actuator. As pressure enters the controller it is held up from going to the actuator until it reaches the adjusted pressure set point (boost psi that you choose). It then releases the pressure to the actuator to control boost. These controllers work on both internal and external style waste gates.
The boost controller comes with the stainless steel mounting bracket, directions, 15 inches of correct size vacuum hose and 4 zip ties.
