GFB Respons TMS T9019 – Weld-On Blow Off / Diverter Valve

The Respons TMS T9019 is GFB's adjustable-bias blow off valve on a universal weld-on base, for custom intercooler piping, aftermarket turbo kits and any application where no direct bolt-on GFB valve exists. Weld the supplied base to your pipe and you get the full Respons feature set: tune the sound from fully recirculated to fully atmospheric, and keep the turbo spinning between shifts.

Smarter than a dual-port BOV

On the surface it looks like a dual-port valve, but a conventional dual-port splits flow at a fixed ratio. The Respons uses GFB's venting bias system – a simple adjuster that moves the split anywhere between 100% recirc and 100% atmosphere. On MAF-metered cars you keep enough recirculation to avoid stalling and rich-running while still getting the sound you want; on MAP-based or speed-density cars you can go full atmosphere.

Why fit a Respons

  • Adjustable venting bias – choose your sound without compromising driveability
  • TMS (Turbo Management System) – holds the valve shut harder on-boost and re-seals faster after a shift for quicker boost recovery
  • No boost leaks – the piston is pressure-balanced so it stays closed at any boost level with the standard spring
  • Quick-release trumpet – swap trumpets or adjust the bias in seconds
  • Billet aluminium, CNC machined and assembled in Australia

A bit of history

GFB released the original Respons in 1999 and refined it with the TMS adjuster in 2001 – the first production BOV with user-adjustable venting bias. The T9019 brings that design to custom applications.

Is there a bolt-on version for your car?

If a direct-fit Respons exists for your vehicle it's the easier install – see the bolt-on range for Subaru (T9000 / T9003 / T9001 / T9007), Mitsubishi Evo (T9002), Nissan (T9004 / T9009), Mazda (T9005 / T9010), Ford Falcon XR6 Turbo (T9008) and VAG (T9359 series). Want the venting adjustable from inside the cabin? Step up to the electronic GFB-T9519 Deceptor Pro II weld-on.
