GFB’s DV+ solution couldn’t be simpler – keep what works and replace what doesn’t.

GFB’s DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles.

By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-oriented product that offers the following benefits:
-Sharper throttle response
-Faster boost recovery on gearshift
-Solves boost leaking issues
-Built to last

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 anodised billet aluminium 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. Read all about the DV+ story below. Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve. This approach requires long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus 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. Oh, and it doesn’t require different springs or frequent re-builds either
