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.
