A factory internal wastegate actuator is the weak point on almost every stock turbo — the diaphragm flexes early and boost creeps or drops off at the top. A Turbosmart IWG actuator replaces it with a billet body, a stronger spring and adjustable pre-load, so the gate stays shut until you want it open. Bolt-on, reuses the factory mounting.
