The JB4 is the most advanced and highly featured tuning system available for your 2022-Present Toyota Tundra 3.4L. Power gains are up to 60hp to the wheels (75hp crank) on a completely stock car on pump gas, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher.
The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with any other Tundra tune. Including on the fly in dash map switching between factory and various performance maps, boost limiting by gear for improved traction in lower gears, built-in data logging, built-in code reading, and much more.
Remember the JB4 Tundra tuner does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for those who are interested in logging, adding new features as we post them, changing maps, etc, we suggest the BMS DATA cable or the Bluetooth mobile phone adapter.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.

What is a JB4?
The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and it's DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.
