The Turbosmart IWG75 internal wastegate actuator is an upgraded actuator for Mitsubishi Evolution 6–8 turbochargers, supplied here as an 18 psi black unit. Turbosmart says the IWG75 increases the working ratio versus factory actuators to improve boost response across the rev range. The design is intended to provide sharper turbo control and greater sensitivity when managing boost.
