GFB Respons TMS Blow Off Valve

Atmosphere venting BOV won’t work on your car? Try a GFB Respons – you’ll be surprised!

Just another dual-port BOV?

On the surface it may look like just another dual-port blow-off valve, but the Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.

Why is this so important? Two key reasons:

• Adjust how loud the blow-off sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it ANYWHERE in between to suit your preference.
• Get a blow-off sound WITHOUT causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF).

Hold on, it gets better. The Respons isn’t just a noise-maker. It also offers:

• Better throttle response
• Faster boost recovery on gearshift
• Unlimited boost-holding!
