Now you can fine tune your FORGE Turbo Wastegate Actuator to the exact needs of your engine with this complete tuning kit. Your spring valve tuning kit you will find five springs and the associated spring retainer. The strongest spring is the red, followed by the blue, yellow, purple, 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.

Kit includes all springs. Kit is Type 2 - 049.

SPRING RATES:

• Green - 5-8 PSI
• Purple - 9-12 PSI
• Yellow - 13-15 PSI
• Blue - 16-18 PSI
• Red - 19-23 PSI

• Purple = Tuned w/Stock Turbo (124 ABARTH) (11psi crack pressure)
• Yellow = Tuned w/Upgraded Turbo (124 ABARTH) (13psi crack pressure)
• Yellow = Tuned w/ Stock Turbo/Upgraded Turbo (500 Abarth) (13psi crack pressure)
