We got our hands on the brand new GFB DVX Diverter Valve to suit the MK7 Golf R and Audi S3. The DVX has fully adjustable spring tension and percentage of air vented to atmosphere. You can have complete blow off to atmosphere or none at all!

The GFB DVX can be purchased through the AutoInstruct online store. Click here!

      Hi Simon, good pickup. We were doing some testing with a boost gauge. Not recommended as boost reference point however!

      Hi Phil, Any vehicle modification could impact warranty to some extent. This is however easily reversible.
