Whether you're running Haltech, MegaSquirt, Link, Motech, Holley EFI, FuelTech, Hondata, KPro, S300, or Neptune, this solenoid integrates seamlessly with virtually any aftermarket ECU platform you've chosen. Precision boost management means you can dial in exactly the pressure curve your setup needs without compromise.

The kit arrives ready to install with one quality MAC solenoid valve and three brass fittings, giving you everything necessary to regulate boost with electronic accuracy.
