GFB’s DV+ solution 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.

  • Uses a factory solenoid coil for seamless integration
  • Replaces plastic valve parts with metal for reliability and strength – especially important on tuned engines
  • Direct-fit replacement with GFB’s TMS benefits
  • Exclusive “pilot-actuated” valve mechanism for rapid response at high boost

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 exact tolerances.

The result is sharper throttle response and lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Read all about the DV+ story below. 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.
