GFB Go Fast Bits Diverter Valves in Canada
GFB — Go Fast Bits — is the Australian company that fixed the VW/Audi diverter valve. The factory diaphragm valves tear and leak boost; GFB's DV+ keeps the factory solenoid and electronics but replaces the weak internals with a metal piston design that holds boost, sharpens throttle response and never needs the diaphragm replaced again. Around that core fix sits the rest of the line: the DVX with adjustable venting volume, the VTA blow-off valves for owners who want the sound, and boost-control hardware.
Our GFB range is 13 products, and sales are a referendum on the DV+: the DV+ with Pierburg valve leads (17 sold), the DVX follows (11), the classic T9351 DV+ is right behind (22 units), and the VTA serves the sound crowd. Seventy-three orders in 24 months — modest parts, bought constantly, because the problem they solve is universal on tuned and aging EA888 cars alike. If your car feels flat up top or surges oddly, this page is probably your fix.

Frequently Asked Questions
Q: DV+ or DVX — what's the difference?
A: Both fix the factory valve's weakness with the same piston design. The DVX adds adjustable venting — you can dial how much air vents to atmosphere (and sound) versus recirculates. DV+ is the quiet, set-and-forget answer.
Q: Will a DV+ help a stock car?
A: Yes — it holds boost better than a tired factory valve and sharpens response even at stock boost; on tuned cars it's close to mandatory. It also never wears out a diaphragm again.
Q: Does the VTA hurt performance?
A: On these metered-airflow cars, a full-vent valve can muddy part-throttle behaviour; the DVX exists precisely to give adjustable venting without the compromises. We'll steer you by how you drive.
