At GP Performance we offer different tuning stages for your GT86 / BRZ. You don't need necessarily a supercharger kit to receive a better performance. Up to stage 5 we offer different options to improve your engine performance without a supercharger kit. When you tend to a HKS v2 Supercharger Kit, you receive at least 100hp over stock on the lowest tuning level.
