Selling the JB4 from my 2021 3.0. $400 OBO shipped, local to San Diego CA. I took it off before I traded in the car, it works flawlessly. There's some adhesive residue from how I had it mounted in the engine bay.

I'd like to keep retain my lifetime powertrain warranty but I am okay with losing it. I understand there is some risk but I'm thinking I'm not wanting a lot of extra torque/hp and I can fix cars myself if anything happens. In the future, I'll go crazier with mods as the platform develops. I'm...

Hey all, I am in the process of obtaining the JB4 + xHP and was wondering would it be better to install xHP first or JB4? Also which OTS maps would you guys recommend for running both? Tried searching on here but couldn't find an answer about anyone running both, everyone seems to go custom map...

Hello just curious what everyones AFRs are at . Currently im using jb4 with a custom map and they're right around 14.5 roughly. I've read that this is normal since the ecu targets that stock.

Hi! finally got the Jb4 in. 21 supra 2.0 running on e15 same tank for both logs. Only have AWE catback exhaust. Map 2: I believe my log looks okay, but I feel like my boost peaks way too high. And is my AFR sitting in the right space or do I need to target a richer mix? Something just feel...
