MACH 2: 100% Recirculating Diverter Valve

The Simple & Essential Mod for Quicker Boost Response

The GFB Mach 2 uses proven TMS technology to provide dependable boost holding and optimum throttle response.

Why Choose the Mach 2?

• Silent Performance: Prefer no blow-off sound or a stealthy setup? The Mach 2 delivers maximum performance without any noise.
• 30% Faster Boost Recovery: GFB's TMS technology allows the Mach 2 to return your engine to peak boost up to 30% faster when shifting gears.
• Easy Installation: The Mach 2 comes in universal and bolt-on kits for most turbo models, requiring no additional parts or modifications. Just replace the factory bypass valve with the Mach 2—easy as that!

Why Upgrade from the Factory Valve?

Factory bypass valves often fall short due to:

1. They blow open above a certain pressure to protect the engine, limiting performance.
2. They are not optimized for quick throttle response, leading to slower boost recovery.

The Mach 2 solves both issues with a pressure-balanced design that can handle unlimited boost and TMS technology for faster throttle response.

Choose the GFB Mach 2 for high performance without the noise.
