Atmospheric dump valve for the 2015-on Ford Mustang 2.3 Ecoboost. The Forge Motorsport atmospheric dump valve for the 2015-on Ford Mustang 2.3 Ecoboost. The stock Ford valve is now a standard electronic solenoid type which we have seen failures of on other vehicles over the past few years. Our valve solution fully integrates with the ECU so that it still thinks the original valve is connected to the car, yet when it activates the valve, you now get the traditional dump valve whoosh accompanying your gearchanges. Also our valve is fully serviceable, and rebuildable with a stronger spring should you increase the boost pressure with a remap.The item "Mustang 2.3 Ecoboost Forge Atmospheric Dumpvalve" is in sale since Friday, February 12, 2016.
