What does the GFB DV+ do?
A GFB DV+ ensures that all your hard-earned boost makes it to the engine and onto the tarmac. Unsurprisingly, the moulded plastic valve components in the factory electronic diverter valve don’t seal that well. The DV+ is the opposite of a blow off valve spacer – it offers performance and reliability improvements over the factory diverter valve, but it does not make a blow off sound. GFB’s VTA and DVX range however do offer a blow off sound AND the same performance improvements of the DV+.
