Go Fast Bits offers DV Plus Range with Direct-Fit Performance Diverters for a wide range of domestic and import vehicles. GFB's DV+ solution couldn't be simpler: keep what works and replace what doesn't. GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great—the ECU opens it faster than any pneumatic valve, so why replace it? The weak point, however, is the valve mechanism itself. GFB's DV+ solves this problem by replacing the valve parts with an anodized billet aluminum housing, fitted with a brass piston machined to exacting tolerances. The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Other manufacturers' products involve replacing the entire system with a traditional pneumatic valve, or include a solenoid valve with the diverter. These approaches add unnecessary cost and additional parts (in some cases requiring long vacuum hose runs, mounting brackets, etc.). All these additional items result in a product that is slower, less responsive, more expensive, and takes longer to install. GFB's DV+ solution, on the other hand, is more responsive, less expensive, easier to install, and doesn't cause compressor surge/turbo flutter. Oh, and it doesn't require different springs or frequent re-builds, either. Order the model recommended for your vehicle.

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!
