JB4 19 Performance Tuner

The Burger Group 19 JB4 is a user-adjustable, plug-and-play performance tuner specifically designed for EA888 Gen4 based models featuring electric assist. It seamlessly integrates with your vehicle's sensors and ECU, manipulating performance through advanced connection points and processing. This tuner is not VIN-locked and can be easily removed or resold. This JB4 unit includes the JB4PRO adapter and free app for wireless connectivity to iOS or Android devices via Bluetooth 4.0. This allows for recording and analyzing vehicle data, changing performance maps, and updating firmware. The free app features an intuitive interface, help buttons, and advanced log analysis tools to estimate performance and identify tuning concerns. Key features and benefits include significant power gains, with an expected 35hp and 50ft-lb on 91 octane and 45hp and 60ft-lbs on 93 octane with a conservative tune. It improves 0-60 and quarter mile times, offers multiple tuning maps for different fuel types, and supports E85 ethanol blends. Installation is quick and plug-and-play. The JB4 also reads and deletes fault codes, displays and logs up to 40 engine parameters, and provides boost-by-gear control for improved traction. It offers better performance and safety than basic chip tunes, boasts full CANbus integration, and runs as smoothly as stock with no impact on fuel economy during normal driving. A minimum of 91 octane is required for performance gains. The unit is housed in a billet aluminum enclosure, designed and assembled in the USA, and comes with a 5-year warranty. Fitment is for the 2021+ VW Taos 1.5TSI (North American model only) and the 2022+ VW Jetta 1.5TSI (North American model only).
