JB4 Performance Tuner

The Burger Motorsports JB4 Performance Tuner is a plug-and-play device designed to enhance the performance of turbocharged vehicles by manipulating boost, timing, and fueling through connections to the car's sensors and ECU. It offers advanced features such as a programmable CANbus system, upgradable firmware, and comprehensive data logging. The JB4 can also read and clear diagnostic trouble codes and incorporates safety measures to protect the engine. This tuner provides a significant performance upgrade with potential gains of up to 100hp and 100tq to the wheels on a stock vehicle, improving 0-60 times and 1/4 mile times. It comes preloaded with custom tuning software and offers up to eight maps for various fuel types and modification levels, including compatibility with Ethanol (E85) mixtures. The JB4 operates smoothly, maintaining stock-like drivability during normal driving and leaving fuel economy unchanged. The JB4 features rugged billet aluminum construction and includes a 5-year warranty. Enhanced functionality is available with the optional JB4PRO system, which adds built-in Bluetooth for smartphone control via a free app, allowing for map changes, data analysis, and firmware updates. The JB4PRO also offers integrated ethanol sensor processing, CPI/WMI control, and ports for additional sensors. Vehicle Fitment includes: 2018-2023 KIA Stinger GT, GT1, GT2 3.3L Turbo; 2018+ Genesis G70/G80 3.3L Turbo; and 2017+ Genesis G90 3.3L Turbo. 91 octane fuel or better is required for performance gains. Spark plugs with more than 25k miles may require upgrading for higher boost levels.
