Now you can fine tune your Turbo Actuator to the exact needs of your engine with this complete tuning kit.
Your valve tuning kit you will find four springs and the associated spring retainer.
The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest.
We normally supply our actuators, unless requested differently, with a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the actuator characteristics to suit a given application.
