Turbosmart 12 PSI Internal Wastegate Actuator for 2015, 2016, 2017, 2018, 2019, 2020 and 2021 EcoBoost Mustangs.

Improve your 2015-2021 EcoBoost Mustang's performance with this 12 PSI Internal Wastegate Actuator from Turbosmart. It 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 your S550's factory actuator. This will give you smoother delivery of power and less turbo lag.

This actuator is designed specifically for modified and tuned Mustangs. You can expect a 3 to 4 PSI (peak boost) increase but the real improvement is in the mid-range.  Turbosmart's Internal Wastegate Actuator is more durable than your S550's stock wastegate actuator. It's also very customizable with interchangeable springs for a range of boost levels, so it can allow your EcoBoost engine to reach its full potential.

Features of the Turbosmart 12 PSI Internal Wastegate Actuator (TS-0622-8122):
- Silicone diaphragm with Nomex reinforcement to withstand high temperatures
- Made out of premium grade billet aluminum
- Corrosion resistant stainless steel rods and connecting clevis
- Locking collar design cap allows for quick spring changes

Your Mustang's stock actuator is made out of stamped steel and fitted with soft springs and a small diaphragm. This results in weak response and significant boost drop off at the top end because the wastegate is easily forced open by exhaust pressure. Turbosmart's 12 PSI option features a higher base pressure, designed for tuned Mustangs running increased boost. The higher spring pressure helps prevent the wastegate being forced open by exhaust pressure at upper RPMs. This actuator offers a big boost in performance because boost comes on sooner and holds on longer.

Please Note: The 12 PSI option is designed for professionally tuned vehicles running increased boost.

*This Internal Wastegate Actuator is not compatible with a stock vehicle. For stock to lightly modified vehicles, we recommend the 7 PSI (TS06228072) or 10 PSI (TS06228102) options.

We’re here with this Turbosmart internal wastegate actuator fitting your 2015 through 2017 Mustang EcoBoost. This Turbosmart internal wastegate actuator is going to be a high-performance upgrade on the factory piece on all 2016 through 2017 EcoBoost Mustangs. This is a 12 PSI wastegate, which is going to allow for a much flatter boost curve and allow the power to come in a lot sooner, and also be a lot smoother. This will give you approximately three to four PSI over the stock set up. This is definitely designed for a tuned or high boost application with a custom tune. It features billet construction with a silicone diaphragm. It will be a direct bolt-on replacement for the factory piece. Again, this 12 PSI version is designed for higher boost applications. For a stock set up, we recommend the 7 PSI version, also available at CJPonyParts.com.
