4th gen + BOV

[JR760]

Anyone aware if the 4th gen BOV can be upgraded, or added. Even a diagram of the engine and it's location would be appreciated. What mounts it uses, etc.

BOV?

BOV?

Blow off valve. For turbo noises.

I would not, this is more for a performance car and even then I would not chose to go atmospheric. A lot of air, in between shifts or letting off accelerator, gets circulated back into the air intake system after the MAF.

It’s got an electronic waste gate, I believe a bov would cause some issues and make it run like shit. Then again, I have seen videos of them on the new tundra and they also have electronic waste gates.

Why would you want to modify your truck on something so crucial? You’ll void the warranty and risk damaging the truck

Asking questions before doing something is a problem? Ultimately, if I get enough information and it doesn't hurt the vehicle then I may proceed. There are fully circulating BOV's for modern OEM turbos.. Just trying to see what options are available.

I know the Tundra had an electronic stepper motor wastegate, but the 2025 Tacoma I have clearly has a standard diaphragm style with a 2 port boost control solenoid. Not that it really makes a difference when upgrading the BOV. If you were to upgrade the BOV, you'd want one that still recirculates. On engines that you run a vented BOV, it's best to switch from MAF to speed density so that metered air doesn't escape and cause a rich condition on throttle lift.

Can count on the Subaru guy to know!
