The GFB Respons, known for its exceptional performance, offers more than your typical dual-port blow-off valve. It distinguishes itself through GFB’s patented venting bias adjustment system, allowing precise control over air venting from both of its outlets. This feature holds immense importance for two key reasons:

  1. Adjustable Blow-Off Sound: Users can precisely tune the blow-off sound to their preference. This means you can either recirculate all air for silent factory operation or vent it all to the atmosphere for maximum noise, or choose any level in between.

  2. Enhanced Performance without Complications: The GFB Respons not only delivers an appealing sound but also offers improved throttle response, faster boost recovery during gearshifts, and unlimited boost-holding capabilities.

The GFB Respons boasts GFB’s TMS (Turbo Management System) principle, designed to return the engine to peak boost up to 30% faster than a factory diverter valve during gearshifts. The innovative venting bias adjustment system works by twisting the adjustment ring to control venting ratios, allowing adjustments from 100% recirculation to 100% atmosphere and everything in between.

The Respons is available in a wide range of universal and direct bolt-on kits. When they say "bolt-on," they mean it, with everything included for a direct fit in the factory location, requiring no car modifications.

GFB has a rich history with dual-port BOVs, pioneering the design in 1999 and introducing the patented venting bias adjustment system in 2001. This technology is not just a gimmick; it's the key to achieving a blow-off sound without the negative issues associated with other valves, and it is exclusive to GFB.

The Respons addresses concerns regarding venting to atmosphere and the impact on cars with airflow meters. By controlling the amount, timing, and duration of the valve's venting, the Respons can vent air to the atmosphere without causing negative side-effects. Competing products that lack this adjustability are unable to achieve similar success on sensitive engines.

Furthermore, the GFB Respons stands out in terms of performance improvement:

1. Boost Holding: Unlike factory bypass valves and other brands that may require different springs for various boost levels, a GFB valve cannot be forced open by high boost. Its balanced piston design utilizes boost pressure to cancel out opposing forces, ensuring all boost is delivered to the engine.

2. Throttle Response and Boost Recovery: GFB's TMS principle differs from factory bypass valves. While a factory bypass valve remains open until required to shut, a GFB TMS valve remains shut until required to open. This operational distinction allows the GFB valve to vent only when necessary, preserving some boost pressure during gearshifts. When the throttle is reopened, peak boost is reached faster than if all pressure is lost, as often occurs with factory valves that remain fully open for extended periods.
