Turbosmart has 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 10psi 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 drivable car with smoother power delivery and less turbo lag. This actuator is ideal for modified and tuned vehicles. You can expect an increase of 1 to 2psi (peak boost) but the real improvement is in the mid-range. Turbosmart's Internal Wastegate Actuator is stronger and more durable than the stock wastegate actuator, and is highly tunable with interchangeable springs for a range of boost levels, so it can allow the EcoBoost engine to release its full potential.
