By combining the proven performance benefits of our ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe VTA shares the successful DV+ design philosophy:\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e“Keep what works, replace what doesn’t”\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThis means we retain ECU control and the solenoid from the factory diverter to ensure the fastest possible response time, without the added and unnecessary cost of replacing the solenoid like some brands do.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe weak part of the factory diverter has always been the plastic valve mechanism – this is the part we replace. The VTA features CNC machined billet components that last a lifetime, and we also change the valve operation method for better performance. The factory diverter valve can only operate in two states – open, or closed. When it opens fully at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eGFB pioneered the use of “pilot operation” in the DV+, which works by re-purposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIt is this design philosophy that makes the VTA not only the best performing blow off valve solution, but also the best value on the market.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eKey features:\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eTMS Technology for faster boost recovery on gearshift and during throttle modulation\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eImproved boost holding ability\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAtmosphere venting for blow-off sound\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRetains ECU control\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSimple, direct bolt-on kits include everything you need to install\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eManufactured in Australia in accordance with ISO 9001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-mce-fragment=\"1\"\u003eVTA or DV+?\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eDepends if you want sound or not. Both valves are constructed with the same quality materials and valve mechanism, and both offer the same performance and reliability benefits.

But that’s it. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesn’t change the diverter valve in any way.
