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 – you might just be pleasantly surprised!

Not Just Another Dual-Port BOV

At first glance, the Respons might seem like just another dual-port blow-off valve. But trust us, it’s so much more! With GFB's innovative patented venting bias adjustment system, you can take charge of how much air vents from each outlet. Let’s break down why this is a game-changer:

• Customize Your Sound: Want it quiet? Recirculate all the air for a factory-silent operation. Craving that loud, attention-grabbing blow-off sound? Vent it all to the atmosphere. You can even find the perfect balance anywhere in between!
• Say Goodbye to Common Issues: Enjoy the iconic blow-off sound without worrying about stalling, backfiring, or any of those pesky BOV-related problems, even if your car has a sensitive airflow meter (MAF).

But Wait, There’s More!

The Respons isn't just about making noise; it brings a whole host of benefits to the table:

• Improved throttle response
• Faster boost recovery when shifting gears
• Unlimited boost-holding capabilities!

For instance, using GFB's Turbo Management System (TMS) principle, tests show that the Respons can return the engine to peak boost up to 30% faster than a factory diverter valve when you shift gears. How cool is that?

How Does the Venting Bias Adjustment Work?

It’s simple! By twisting the adjusting ring, you can open the atmo port while simultaneously closing the recirc port. This gives you a range of venting ratios from 100% recirc to 100% atmosphere, and everything in between. Talk about versatility!

Easy Installation

When we say "bolt-on," we mean it! Everything you need comes included, and it fits directly into the factory location—no separate adapter required and no modifications to your car!
