GFB T9004 Respons Adjustable BOV Blow Off Valve Diverter with TMS

The GFB Respons T9004 is an advanced blow-off valve and diverter system engineered to improve throttle response and reduce turbo lag on turbocharged vehicles. Featuring GFB's proprietary Turbo Management System (TMS), this 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 venting bias adjustment that allows you to infinitely vary the air vented between recirculation (silent) and atmosphere (audible blow-off sound). This stereo-style volume control lets you dial in the exact sound level you want. By fine-tuning the venting ratio, you can achieve an atmospheric 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:

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

Ideal Applications:

• VAG (Volkswagen Audi Group) and other MAF-sensitive vehicles
• Enthusiasts wanting adjustable blow-off sound without CEL issues
• Performance builds requiring quick throttle response and minimal turbo lag

The GFB Respons T9004 combines proven performance technology with user-adjustable sound control, making it the ideal choice for drivers who want both function and an engaging audible experience from their turbocharged vehicle.
