Go Fast Bits offers Mach 2 TMS Recirculating Diverter Valves for a variety of vehicles. It's the simple and essential modification for 30 percent quicker boost—utilizing proven TMS (Turbo Management System) technology to ensure dependable boost holding and optimum throttle response. If you don't need the patented venting bias adjustment feature of the Respons or Deceptor Pro, the Mach 2 is your answer. It's configured as a 100 percent recirculating valve (i.e. bypass, plumb back), and add-on kits are also available to convert to 100 percent atmosphere venting. Use the recirc model for direct factory replacement when you want the performance without the noise—or add the conversion kit when you want some noise with your performance! Factory bypass valves have two main shortcomings: they're typically designed to start opening above a certain pressure to protect the engine, and they're not optimized for throttle response. And you can't vent them to atmosphere without stalling your engine. The Mach 2 solves all of these issues. It can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response. And you CAN vent with the atmo conversion to atmosphere without stalling your engine. Product notes: * Recirculation model for direct factory replacement for performance without the noise * Atmosphere venting kits to convert the recirculating valve if you want noise with your performance * Like the Respons and Deceptor Pro II, the Mach 2 is available in a range of bolt-on kits for most popular turbo models * No additional adaptors, parts or vehicle modifications are required—simply remove the factory bypass valve and replace it with the Mach 2; it's that simple!
