GFB T9135 Mach 2 Diverter Valve with TMS Technology and Atmosphere Conversion Option

The GFB Mach 2 T9135 is a high-performance diverter valve engineered to dramatically improve throttle response and boost recovery on turbocharged engines. Using GFB's patented TMS (Turbo Management System) technology, the Mach 2 returns the engine to peak boost up to 30% faster than factory diverter valves during gear changes, delivering sharper acceleration and reduced turbo lag.

Key Features:

• TMS technology for optimized throttle response and faster boost recovery
• True bolt-on installation with no additional adapters or modifications required
• Unlimited boost holding capacity - engineered to handle any boost pressure a turbo can produce
• 100% recirculating configuration for silent, factory-style operation
• Optional atmosphere conversion kit available for audible blow-off valve sound
• Vents to atmosphere without causing engine stalling (with conversion kit)
• Direct replacement for factory bypass valves on most popular turbocharged models

The Mach 2 addresses the key limitations of factory bypass valves, which are typically designed to open at specific pressures for engine protection rather than performance optimization. This valve can effectively hold unlimited boost while maintaining peak throttle response. It ships configured as a 100% recirculating valve for quiet operation and emissions compliance, but can be converted to atmosphere venting with an optional conversion kit when you want the classic turbo blow-off sound without compromising drivability.

Available in vehicle-specific bolt-on kits that install in minutes with basic hand tools - simply remove your factory bypass valve and bolt the Mach 2 in its place.
