Description
Transform your 2020+ Toyota GR Supra Mk5 into a performance beast with the JB4 Tuner. Designed for both the B58 3.0L inline-6 and B48 2.0L inline-4 engines, the JB4 delivers unparalleled power gains of up to 100 horsepower at the crank (80hp to the wheels) on a completely stock vehicle running pump gas. With its cutting-edge technology and innovative features, the JB4 is the ultimate tuning solution for enthusiasts seeking enhanced performance without compromising reliability or safety.
The JB4 is a true plug-and-play system, ensuring hassle-free installation and removal. It offers advanced features such as on-the-fly in-dash map switching, boost-by-gear adjustments, built-in data logging, code reading, and compatibility with ethanol (E85) fuel blends. Its CANbus OBDII integration provides precise control over engine parameters, resulting in smooth, factory-like drivability in all driving modes while unlocking massive performance potential.
Unlike traditional flash tuning, the JB4 leaves no trace on your ECU and is not VIN-locked, allowing you to remove it without a trace or resell it down the road. The JB4 also supports wireless connectivity via the optional JB4 Mobile Connect Kit for iOS/Android devices or through a Windows laptop with the BMS Data Cable. This enables you to fine-tune performance maps, record real-time engine data, and update firmware with ease.
For Supra owners seeking bolt-on upgrades or running higher-octane fuels, the JB4 offers even greater power gains, ensuring your Supra remains at the cutting edge of performance. With a durable billet aluminum enclosure and a five-year warranty, the JB4 is built to last, offering unmatched tuning flexibility and value.
