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

Are you struggling to find an atmosphere venting BOV that works for your car? Give the GFB Respons a try—you might 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 it’s so much more than that! With GFB's patented venting bias adjustment system, you can fine-tune how much air vents from each of the two outlets. Let’s talk about why that matters.

Why Venting Bias Adjustment is a Game Changer

• Control the volume of your blow-off sound. Choose to recirculate all the air for a quiet factory-like operation, vent it all to atmosphere for maximum noise, or set it anywhere in between to match your style.
• Achieve that satisfying blow-off sound without the worry of stalling, backfiring, or other BOV-related issues—even if your car has a sensitive airflow meter (MAF).

But Wait, There’s More!

The Respons isn’t just about making noise; it offers some fantastic performance benefits too:

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

For instance, using GFB's Turbo Management System (TMS) principles, tests indicate that the Respons can return your engine to peak boost up to 30% faster than a factory diverter valve during gear shifts. Want to know more? Read on!

How GFB's Patented Venting Bias Adjustment Works

Simply twist the adjusting ring to open the atmosphere port while simultaneously closing the recirculation port. This allows for venting ratios that range from 100% recirc to 100% atmosphere, and everything in between.
