GFB T9035 Respons Adjustable Blow Off Valve BOV Diverter with TMS

The GFB Respons T9035 is a high-performance blow-off valve and diverter valve designed to improve throttle response and reduce turbo lag on turbocharged vehicles. Engineered with GFB's Turbo Management System (TMS), this advanced valve returns the engine to peak boost up to 30% faster than factory diverter valves during gear shifts, delivering noticeable performance gains.

Patented Adjustable Venting Bias System:

The Respons features GFB's unique adjustable venting bias system that allows you to infinitely vary the amount of air vented between recirculation (silent) and atmosphere (audible blow-off sound). This adjustment works like a volume dial, letting you fine-tune the venting ratio to achieve your desired sound level while maintaining proper engine operation. By carefully adjusting the bias, you can achieve blow-off sound without triggering check engine lights, running rich, stalling, or experiencing the fuel economy issues commonly associated with atmospheric venting on MAF-equipped vehicles.

Key Features:

• Advanced Turbo Management System (TMS) for reduced turbo lag and improved throttle response
• Spring pre-load adjustment for maximum response tuning
• Full progressive bias adjustment from recirculation (silent) to atmospheric venting (loud)
• Manual bias adjustment via external cap ring for easy tuning
• Can be locked in full recirculation mode for emissions compliance
• Available in universal hose-mount or direct bolt-on configurations

Ideal Applications:

• Vehicles with MAF sensors sensitive to atmospheric venting (especially VAG/Volkswagen Group applications)
• Performance enthusiasts who want both sound control and maximum throttle response
• Applications requiring quick and easy venting bias adjustment
• Installations where emissions compliance may be required

The GFB Respons combines proven performance technology with user-friendly adjustability, making it an excellent choice for turbocharged vehicles where both performance and sound customization are priorities.
