:You can still have the adjustability from a native boost of 12 psi to wide open 25 or 26 psi. You just need a stronger spring to keep it closed. Since you have a stronger spring, you need a larger surface area in the actuator to let that same native boost overcome the spring to open the wastegate.
Are you saying the HKS actuators have more surface area than the stock units? The cans look about the same size to me...
