Description
The Burger Tuning JB4 Tuner for 2023+ Toyota Highlander, Crown, and Vellfire 2.4L Turbo delivers up to 40hp to the wheels (55hp crank) on a stock vehicle running premium pump gas—without the risks of ECU flashing. No ECU unlock required, making it fully compatible with Toyota’s latest locked ECUs.
Featuring plug-and-play installation, the JB4 offers advanced tuning capabilities not found in competing systems. Enjoy on-the-fly map switching, boost limiting by gear, progressive water/methanol support, data logging, and built-in diagnostic code reading. Other tuners may claim similar technology but lack the JB4’s deep feature set, safety systems, and long-term support.
Best of all, the JB4 requires no additional modifications—install it as your first performance upgrade and transform your vehicle instantly. For those who want more control, add our optional Bluetooth adapter to change maps, log runs, and update firmware directly from your smartphone.

What is a JB4?
The JB4 is a plug-and-play performance tuner for turbocharged vehicles. It installs between your vehicle’s sensors and ECU to enhance boost, fueling, and timing for safe, reliable power gains. Unlike basic tuners, the JB4 uses CANbus data, fuel and spark control, and advanced algorithms to maximize performance while maintaining factory-like drivability. With free firmware updates, multiple map options, and easy removal, the JB4 remains the industry standard for over a decade.
