How do I change the venting configuration on this blow-off valve?

The Go Fast Bits Hybrid TMS valve comes with a pair of blanking plugs. You can use these plugs to set the valve for full recirculation, a 50/50 mix of atmosphere and recirculation, or full atmosphere venting to achieve your desired sound.

Will this valve cause issues with my car's airflow meter?

No, this valve is specifically designed to be used on cars with sensitive airflow meters. Its dual-venting design helps prevent common issues like backfiring and stalling that can occur with other types of blow-off valves.

What is TMS technology?

Product Details

If you're working on your 1989-1996 Nissan 300ZX and looking to upgrade the blow-off valve, this Go Fast Bits Hybrid TMS Dual Port model is a solid option. This valve combines both recirculating and atmosphere venting capabilities, which is a big help for cars with sensitive airflow meters. It helps prevent issues like backfiring or stalling while still giving you that distinct blow-off sound.

What makes this valve unique is its dual-stage venting. At low valve lifts, most of the air is recirculated, keeping things smooth. As the valve opens further under harder driving, more of the atmosphere venting port is exposed, creating that signature sound. Plus, GFB includes a pair of blanking plugs, so you can easily switch between full recirculation, a 50/50 mix, or full atmosphere venting to get the sound you want. The TMS technology also helps with faster boost recovery after shifting gears, potentially improving performance by up to 30%.

This is a direct bolt-on part for your 300ZX, meaning installation should be straightforward without needing custom fabrication. It's a well-built piece designed to integrate smoothly with your existing setup.
