MACH 2: 100% Recirculating Diverter Valve

THE STRAIGHTFORWARD AND INDISPENSABLE UPGRADE FOR ENHANCED BOOST RESPONSE

Employing Proven TMS Technology for Reliable Boost Holding and Optimal Throttle Response

If the typical blow-off sound doesn’t align with your preferences, and you’re aiming for the stealthiest turbo upgrade possible, the GFB Mach 2 is the ideal choice! Designed with GFB’s TMS technology, the Mach 2 contributes to restoring the engine to peak boost up to 30% faster than a factory diverter valve during gear shifts (further details below).

The Mach 2 is offered in a variety of universal and bolt-on kits tailored for most popular turbo models. When we say “bolt-on,” we mean precisely that! No extra adapters, components, or vehicle alterations are necessary – just remove the factory bypass valve and swap it with the Mach 2 – it’s that straightforward!

Configured as a 100% recirculating valve (bypass, plumb back), the Mach 2 serves as a direct factory replacement when you desire top-notch performance WITHOUT the accompanying noise!

Wondering why you should replace the factory bypass valve? Improved performance! Factory bypass valves often have two key drawbacks – they are frequently designed to open above a specific pressure to safeguard the engine, and they are not optimized for optimal throttle response.

The Mach 2 effectively addresses both issues. Featuring a pressure-balanced design, it can securely hold unlimited boost (considering no turbo could generate sufficient pressure to cause damage), while the TMS technology ensures peak throttle response.
