Can I adjust the sound of the blow-off valve?

Yes, the GFB Hybrid TMS valve is designed for adjustable sound. It comes with blanking plugs that allow you to configure it for full recirculation, a 50/50 split, or full atmosphere venting to achieve your desired sound level.

Will this valve work with my car's airflow meter?

This valve is designed to be used on cars with sensitive airflow meters. Its dual outlet design helps prevent issues like backfiring and stalling that can occur with other types of blow-off valves on these systems.

Product Details

Go Fast Bits is known for creating well-built performance parts, and their Hybrid TMS Dual Port valve is a prime example. If you're working on your 1989-1998 Nissan 240SX, this blow-off/diverter valve is designed to manage boost pressure effectively. It's a dual outlet valve that combines recirculating and atmospheric venting, making it suitable for vehicles with sensitive airflow meters that might otherwise experience issues like backfiring or stalling, all while still giving you that signature blow-off sound.

What makes this valve unique is its staged venting system. At low valve lifts, most of the air is recirculated, but as you drive harder and the valve opens further, more of the atmosphere venting port is exposed, which changes the sound. GFB includes a pair of blanking plugs, so you can easily configure the valve for full recirculation, a 50/50 split between recirc and atmosphere, or full atmosphere venting to get the sound you want. Plus, the TMS technology helps with up to 30% faster boost recovery when you shift gears.

This is a direct fit bolt-on part for your S14/S15 Silvia/200SX, meaning installation should be straightforward. It's a solid option if you're looking to fine-tune your turbo system's performance and sound.
