HKS actuator kit provides rod length adjustment to provide better boost control up to 1.0bar of boost manually. Boost range higher than 1.2bar can be achieved with aide of aftermarket boost controllers to direct signals to the wastegate actuator for higher boost pattern. It is recommended to upgrade the stock actuator for people looking to boost at or beyond 14psi. Adjustment should be done carefully with couple turns at a time.
* Please select the appropriate model of your motor when ordering. When adjusting the rod, plese use a pressure pump to test the pressure rating which the wastegate opens and closes to your desirable boost pressure. For people that doesn't have a pressure pump, turn just 2-3 turns at a time and drive the car carefully to see what boost pressure is achieved.
