Go Fast Bits offers DV Plus Diverter Valves with TMS (Turbo Management System) Advantage for a wide range of vehicles, particularly imports. 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?)—but the weak point is the valve mechanism itself. So GFB's DV+ solves this problem by replacing just 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, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum—plus either a different solenoid valve to actuate the pneumatic valve, or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much 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. Order the model recommended for your vehicle. Additional notes: * Retains the factory solenoid coil for seamless integration * Replaces plastic valve parts with metal for reliability and strength on chipped engines * Exclusive "pilot-actuated" valve mechanism for rapid response at high boost
