Introducing The New DV+ For 1.4 TSITwin Charged Engines. 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 only 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
