GFB T9020 Respons Adjustable Blow Off Valve BOV Diverter Valve TMS

The GFB Respons T9020 is a high-performance blow-off valve and diverter valve designed specifically to improve throttle response and reduce turbo lag on turbocharged vehicles. Featuring GFB's innovative Turbo Management System (TMS), this valve returns the engine to peak boost up to 30% faster than factory diverter valves during gear shifts, delivering measurable performance gains.

Adjustable Venting Bias System:

The Respons features GFB's patented adjustable venting bias system, allowing you to infinitely adjust the ratio of air vented to either recirculation (silent operation) or atmosphere (audible blow-off sound). This unique dial-adjustable system lets you fine-tune the venting sound like a volume control, enabling you to achieve the desired blow-off sound without triggering check engine lights, running rich, stalling, or experiencing fuel economy issues commonly associated with atmospheric venting on MAF-equipped vehicles.

Key Features:

• TMS (Turbo Management System) technology reduces turbo lag and improves throttle response
• Spring pre-load adjustment for maximum response and precise tuning
• Progressive bias adjustment from full recirculation (silent) to full atmosphere (loud)
• Manual adjustment via external cap ring for easy tuning
• Can be locked in full recirculation mode for emissions compliance
• Available in universal hose-mount and vehicle-specific direct bolt-on configurations

Ideal Applications:

• Vehicles sensitive to atmospheric venting, particularly VAG (Volkswagen Audi Group) applications
• Enthusiasts seeking adjustable sound control without compromising performance
• Performance builds requiring quick throttle response and reduced turbo lag

The GFB Respons T9020 combines proven performance technology with user-adjustable sound control, making it the perfect choice for enthusiasts who want both measurable gains and audible feedback from their turbocharged vehicle.
