IWG75 2015 Ford Mustang 2.3L EcoBoost 10PSI - TS-0622-8102Turbosmart have designed a brand new Internal Wastegate Actuator for the Mustang EcoBoost, which can help owners get more performance out of their engine with little effort. Turbosmart's Internal Wastegate Actuator creates a flatter boost curve which comes on sooner, with more stable boost and less drop off at the end of the rev range compared to the stock actuator. The result is a more driveable car with smoother power delivery and less turbo lag.
