So, not only do you get improved boost holding and throttle response, you have total control over your blow-off sound volume! The DVX is not just a noise maker (like BOV spacers); by modifying the valve operation method, it offers the same performance benefits that the DV+ does. It retains ECU control for the fastest possible operation. No other blow-off valve has the advantage of GFB's venting bias adjustment, allowing you to alter the blow-off sound simply by moving the adjustment lever. GFB's DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to "pilot actuation" to ensure better performance on stock or modified engines. Furthermore, these benefits won't cost you a fortune! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer's "solutions"), the DV+ keeps what works and replaces what doesn't. Order the model recommended for your vehicle.
