MACH 2: 100% Recirculating Diverter Valve

The Essential Mod for Faster Boost Response

Looking for stealthy performance without the loud blow-off sound? Whether you want a sleeper setup or just don’t want your partner knowing you’ve turbocharged the daily (again), the GFB Mach 2 is the perfect solution.

Why Choose the Mach 2?

• Faster Boost Recovery – Uses TMS technology to restore peak boost up to 30% faster than a factory diverter.
• 100% Recirculating – All the performance benefits without the noise.
• Bolt-On Installation – No adaptors, extra parts, or modifications needed—just swap it in!
• Superior Boost Holding – Unlike stock bypass valves, the Mach 2 won’t leak or blow open under high boost.
• Optimized Throttle Response – Designed for maximum performance and reliability.

Why Upgrade from a Factory Bypass Valve?

Stock valves often suffer from two key issues:

1. They leak under high boost – Many are designed to blow open at a certain pressure, limiting performance.
2. They aren't optimized for throttle response, causing unnecessary lag.

With its pressure-balanced design, the Mach 2 can handle unlimited boost, delivering quicker throttle response and rock-solid reliability.
