JB4 Tuner for 2020-2026 Toyota Supra Mk5

The JB4 is the most advanced and highly featured tuning system for your Toyota Supra Mk5. Power gains are up to 80hp to the wheels (100hp crank) on a completely stock car on pump gas for a B58. 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 tune. Including on-the-fly in-dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4’s technology but, upon closer examination, lack most if not all of the JB4’s features.

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. A separate JB4 Mobile app purchase is also required.

Kindly note the JB4 pro Bluetooth module is sold separately.
