GFB T9012 Respons TMS Adjustable Blow Off Valve BOV Diverter

The GFB Respons TMS (Turbo Management System) is a fully adjustable blow-off valve and diverter valve hybrid that gives you complete control over your turbo's sound and performance. Unlike traditional BOVs that either vent to atmosphere or recirculate, the Respons TMS features a unique adjustable ring that allows you to infinitely vary the balance between recirculated and vented air.

Key Features:

• Fully adjustable venting ratio from 100% recirculation to 100% atmosphere
• Tool-free adjustment ring for quick sound and response tuning
• Dual-port design combines BOV and diverter valve functionality
• High-flow valve body with aluminum construction for durability
• Eliminates compressor surge and reduces turbo lag
• Includes multiple springs for different boost levels
• Direct bolt-on replacement for OEM diverter valves on many applications

Perfect for enthusiasts who want the flexibility to switch between a quiet, recirculated setup for daily driving and an aggressive, atmospheric sound for track days or events. The adjustment can be made in seconds without tools, allowing you to dial in the perfect balance between sound and stealth. The precision-engineered valve mechanism ensures reliable operation across a wide range of boost pressures, while the dual-port design maintains proper air metering for optimal engine performance.
