TurbosmartUpgraded Wastegate Actuators have been developed to provide maximum possible boost response for your factory frame turbocharger. The TurbosmartIWG75 Series of upgraded Actuators benefit from an increased Working Ratio over the factory equipment resulting in improved boost response, throughout the RPM range.

This Improved working ratio is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.

Upgrading with the same base pressure as factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning & recalibration is likely required.
