Description
The BMS JB4 Tuner is the ultimate tuning system for the 2020+ Toyota Supra Mk5. With power gains of up to 80HP to the wheels on a completely stock car on pump gas, you can unlock the true potential of your vehicle. Our advanced tuning system offers a quick and easy plug and play installation with CANbus integration, providing unrivaled tuning features and performance.
The JB4 Tuner also features on the fly map switching, boost limiting by gear, water/methanol support, built-in data logging, code reading, exhaust flapper control, and much more. It runs as smoothly as stock, making it feel like your vehicle came from the factory with it. Compatible with all driving modes, the JB4 Tuner does not affect fuel economy during normal driving.
You can also take advantage of our Ethanol (E85) compatible tuning maps, which offer even higher power gains with bolt on parts, higher octane, and larger turbos. The JB4 Tuner is not VIN locked, meaning it can be removed without a trace and resold down the road.
For even more convenience, the JB4 Tuner is compatible with JB4 Mobile for smartphone logging and tuning changes, allowing 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.
Made in the USA with a 5-year warranty, the BMS JB4 Tuner is the most advanced and highly featured tuning system available for your A90 Toyota Supra. Don't settle for less, install the JB4 Tuner as your first and only modification and enjoy an entirely new fast and smooth racing experience.
