As the name suggests, the GFB Respons is designed specifically with the aim of improving throttle response and reducing turbo lag.

What’s TMS? GFB’s Turbo Management System is the term they apply to their diverter valves that have features designed specifically for the purpose of turbo lag reduction.

Tests show that TMS features can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears.

On top of the TMS benefits, the Respons also packs GFB’s patented adjustable venting bias system found on the Stealth FX.

This unique system allows the amount of air vented to either recirc or atmosphere to be infinitely varied to change the venting sound like a stereo volume dial.

So if you want noise with your performance, the Respons can deliver. By fine-tuning the venting ratio, you CAN achieve a blow-off sound WITHOUT throwing a CEL, running rich, stalling, using more fuel or causing any other problems commonly associated with atmo-venting valves on cars with MAF sensors.

bought this for my 09 WRX wagon. install was quick and easy, it only took me about 5 minutes. the valve itself is great! just make sure you have a high waste gate tune on your car so you don't burn up your cat. great thing about it though is that you can change the blow off by just turning the valve, no tools needed! like the title says, it's a great purchase.

Gfb blowoff valve

Great product as usual from gfb. Great service from rsd. The valve sounds great. Did notice a little drop in fuel efficiency but that's to be expected. I'm still very happy no complaint at all. The install was super easy self explanatory to setup the valve. Love the wish sound.

  • AnswerQ: Tune?  08wrxnoob 3 months ago

    My subaru wrx is stock right now and i was wondering if i would need to tune my car if i set this partially vented. I just dont want to set off the O2 sensor by accident


    • A: A tune will not have any benefit when venting to atmosphere. With your vehicle using a MAF sensor anytime you vent to atmosphere it will have rich spikes on shifts or a lower idle. This can only be remedied by switching to an air density style setup or keeping the valve fully recirculating.

  • AnswerQ: Subaru Legacy GT AT  Psour 3 months ago

    It`s recommended for automatic transmissions?. I would like to hear the whistle in my Subaru Legacy Gt 06


    • A: The Blow off valve is just fine for automatic transmissions as boost still builds the same. This would be a great choice for all turbo models.
