GFB Respons TMS: Smarter Than Your Average Dual Port BOV!

Are you struggling to find an atmosphere venting BOV that works for your car? Look no further than the GFB Respons—it might just surprise you!

What Makes the Respons Stand Out?

At first glance, the Respons may seem like just another dual-port blow-off valve, but it's so much more than that. With GFB's patented venting bias adjustment system, you can fine-tune how much air is vented from each of the two outlets.

Why Adjust the Venting?

Here are two fantastic reasons:

• Control the volume of your blow-off sound. Whether you want a quiet factory operation by recirculating all the air, a loud atmosphere vent for maximum noise, or something in between, you can set it just the way you like.
• Enjoy that blow-off sound without the worry of stalling, backfiring, or other BOV-related issues—even on cars with sensitive airflow meters (MAF).

More Than Just Noise!

The Respons isn't just about the sound; it brings a host of performance benefits too:

• Improved throttle response
• Faster boost recovery during gear shifts
• Unlimited boost-holding capability!

For instance, thanks to GFB's Turbo Management System (TMS) principle, tests show that the Respons can return your engine to peak boost up to 30% faster than a factory diverter valve when shifting gears. How's that for performance?

How Does the Venting Bias Adjustment Work?

It's simple! By twisting the adjusting ring, you can open the atmosphere port while simultaneously closing the recirculation port. This gives you a range of venting options—from 100% recirc to 100% atmosphere and everything in between.

Easy Installation

When we say "bolt-on," we mean it! Everything you need is included, and it fits directly in the factory location—no separate adapters or modifications necessary.
