Anyone still running ITBs on a 1UZ these days?

Individual throttle bodies on a 1UZ are one of those setups that look and sound incredible but live in a niche corner of the community. There used to be a handful of vendors making NA manifolds and ITB kits for these motors. A shop in New Zealand was one of the names that came up regularly years ago.

I'm curious where this stands now.

1. Who's still making ITB manifolds and throttle body setups for the UZ family in 2026?
2. If you're running them, was it worth it for the power, throttle response, and sound versus the cost and the tuning headache?
3. Has anyone done a proper back-to-back, stock plenum versus ITBs, on the same engine?

Less interested in "ITBs are cool" and more in real experience from people who've actually lived with them. The tuning side especially. Getting these dialed in is supposed to be the hard part.
