GFB DVX Adjustable Bias Atmospheric / Diverter Valve
The GFB DVX Diverter Valve has been developed to operate with systems where air mass metering can be problematic.
Whilst there are many spacer valves on the market, these usually eliminate the ECU control completely, relying on vacuum control and only redirect the air in to the atmosphere.
The DVX Diverter valve differs from this by retaining ECU Control, ensuring the fastest possible response even with the smaller throttle transitions, whilst the modified valve operation means that it actually offers performance benefits and an increased flow capacity.
The DVX Diverter is able to solve the longevity and boost leaking issues that are very common with factory diverter valves. Retaining ECU control, the DVX is manufactured to the usual highest GFB spec, ensuring an increase in boost holding and throttle response over a factory diverter valves.
This valve includes dual venting outlets along with GFB's patented Venting Bias Adjustment System, which means you are now actually able to control the volume of the Blow Off sound!
