How do I adjust the sound of the blow-off valve?

You can adjust the venting bias by simply twisting the adjustment ring on the valve. This allows you to change the amount of air recirculated versus vented to the atmosphere, altering the sound from silent to loud.

What is TMS Technology?

GFB's TMS (Turbo Management System) Technology is designed to ensure rapid boost recovery after gear shifts and maintain optimal throttle response. It helps the system perform efficiently under boost.

Product Details

The GFB TMS Respons Blow Off Valve kit uses a patented venting bias adjustment that lets you fine-tune how much air is recirculated back into the intake versus vented to the atmosphere. This means you can get the blow-off sound you want, from completely silent to a loud vent, without causing common issues like backfiring or stalling that can happen with fixed-ratio atmosphere-venting valves. It's designed to work with your factory hoses, though some modification may be needed.

GFB's TMS Technology is built into this valve, which helps ensure quick boost recovery when you shift gears and maintains good throttle response. It's built to handle boost pressures well over 100psi, meaning it can hold more boost than most turbos can produce. The adjustment ring makes it simple to change the venting bias on the fly, giving you control over the sound and performance characteristics.
