GFB 19+ Hyundai Veloster 1.6 GDI Turbo - Forte GT / 16+ i30 SR 1.6T-GDI TMS Respons Direct Fit Blow Off Valve

The Respons TMS Direct Fit Blow Off Valve (T9011) is engineered specifically for Hyundai and Kia 1.6L turbocharged platforms, delivering performance, sound, and reliability without compromise. While it may resemble a traditional dual-port BOV, the Respons is far more advanced, featuring GFB’s exclusive venting bias adjustment system that allows precise control over how much air is vented to atmosphere versus recirculated back into the intake.

This adjustability is critical for modern turbocharged vehicles that rely on sensitive MAF-based engine management. With the Respons, you can run anything from 100% recirculation for factory-silent operation, to 100% atmospheric venting for maximum sound, or any balance in between—without causing stalling, backfiring, rich conditions, or check engine lights.

Beyond sound, the Respons delivers real performance gains. Its balanced piston design allows it to hold unlimited boost pressure without being forced open, unlike factory diverter valves or spring-based aftermarket units. Using GFB’s Turbo Management System (TMS) operating principle, the valve remains closed until venting is absolutely required, preserving boost pressure during gear changes and reducing turbo lag. Independent testing shows boost recovery up to 30% faster compared to factory bypass valves.

The T9011 is a true direct bolt-on upgrade, installing in the factory location with no adapters, no modifications, and no tuning required. Everything needed for installation is included, ensuring OEM-level fitment and reliability.

For drivers who want adjustable sound, sharper throttle response, faster boost recovery, and rock-solid boost control, the Respons TMS delivers performance and drivability that traditional dual-port BOVs simply can’t match.
