GFBs 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 (read about this below) to ensure better performance on stock or modified engines.
Furthermore, these benefits wont cost you the Earth! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturers solutions), the DV+ keeps what works, and replaces what doesnt.
WHY NOT JUST USE A SPACER?
There are many BOV spacers on the market that make noise. However, they do this simply by using the factory diverter valve and redirecting the air to atmosphere. Therefore, the performance deficiencies of the factory diverter valve design remain, and furthermore, the flow capacity of the factory diverter is significantly reduced because of the small venting holes used in these BOV spacers.
ECU VS VACUUM CONTROL
Other BOV kits eliminate the ECU control entirely, using pure manifold vacuum control instead. Whilst theres nothing particularly wrong with this (thats how the majority of BOVs work), the ECU control is MUCH FASTER, able to detect and respond to much SMALLER THROTTLE TRANSITIONS and, since its available, why wouldnt you use it?
WHATS SPECIAL ABOUT OUR VENTING BIAS SYSTEM?
GFBs patented Venting Bias Adjustment System is the only one of its kind in the world. By using an internal rotating sleeve, the opening of both the recirc port and the atmosphere port can be infinitely adjusted. This means that youre not stuck with a fixed 50/50 or 100% atmosphere venting ratio; you can change it to whatever you want! As an additional benefit, because the atmosphere outlet is a single large port rather than a series of small holes, the venting sound is much DEEPER AND LOUDER than it is with a BOV spacer.
THE BOTTOM LINE IS...
The DVX offers a TRUE PERFORMANCE improvement, INCREASED BOOST-HOLDING ability, and a blow-off sound that is COMPLETELY ADJUSTABLE from factory-silent to ear shattering!
