Made in Australia for legendary performance, with a great Blow Off Sound!

Not just a noise-maker, get improved performance too!
If you want sound with your performance (or performance with
your sound!), GFB’s VTA delivers just that! 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.

The VTA shares the successful DV+ design philosophy:
“Keep what works, replace what doesn’t”.

This 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.

The 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.
