Description
The Burger Tuning JB4 for 2023+ Toyota Sequoia 3.4L Twin Turbo is the most advanced and feature-rich plug-and-play tuner available for your i-FORCE MAX Hybrid powertrain. On a completely stock truck running pump gas, you can expect gains of up to +60whp (+75hp crank), with even higher numbers possible when running bolt-on upgrades, higher octane fuel, E85 blends, or upgraded turbos.
With full CANbus OBDII integration, the JB4 monitors over 20 critical engine parameters—such as boost pressure, AFR, ignition timing, gear position, throttle input, and knock feedback—and adjusts boost, timing, and fueling in real time for optimal safe performance. Built-in safety protocols automatically reduce boost if the engine overheats, runs lean, or knocks excessively.
The JB4 includes 8 preloaded maps, allowing you to switch between stock, performance, E85 blend, race fuel, and VALET mode instantly—right from your dash or via the JB4 app. Additional advanced features include boost-by-gear for improved traction, fault code reading/clearing, and real-time data logging.
Paired with the optional JB4 Mobile or JB4PRO wireless adapters, you can monitor live engine data, change maps on the fly, update firmware, and analyze logs directly from your iOS or Android device.

What is a JB4?
The JB4 is a premium plug-and-play tuning solution for turbocharged vehicles.
