EMS – 3-Port Mac Valve Kit for 2015-2023 Mustang EcoBoost 2.3L

Recommended for Big Turbo & High Boost EcoBoost Builds

The EMS 3-Port MAC Valve Kit is designed to improve boost control on turbocharged EcoBoost engines, especially vehicles running upgraded or large-frame turbochargers.

When moving to a bigger turbo, the factory boost control solenoid can struggle to manage boost pressure effectively. A 3-port MAC valve allows your tuner to control the wastegate more precisely, helping stabilize boost and improve turbo response.

This results in smoother power delivery, more consistent boost levels, and improved tuning control for high-performance setups.

For big turbo EcoBoost builds, upgrading to a 3-port boost control system is strongly recommended.

Why Big Turbo Builds Benefit From a 3-Port MAC Valve

• More precise boost control for tuned setups
• Helps prevent boost spikes with larger turbos
• Improves turbo response and boost stability
• Allows tuners greater control over boost targets
• Proven industrial-grade MAC solenoid used in motorsports applications
