JB4 Performance Tuner

The Burger Group 10 is a plug-and-play performance tuner for turbocharged vehicles, designed to enhance power and reduce turbo lag. This system attaches to your car's sensors and DME/ECU, manipulating boost, timing, and fueling to deliver significant performance gains comparable to an ECU reflash, but without altering the factory ECU. It ensures safe operation by maintaining factory safety systems and not requiring ECU unlocking. The JB4 tuner offers a range of features including multiple tuning maps for various fuel types, E85 ethanol blend support, and the ability to read and delete fault codes. It can display and log up to 40 engine parameters, provides boost-by-gear control for improved traction, and manages exhaust flap operation on supported vehicles. The tuner is compatible with the JB4PRO app, allowing for wireless connection via Bluetooth to iOS or Android devices for on-the-fly map changes, data logging, and firmware updates. It also offers better performance and safety than basic chip tunes and ensures smooth stock-like operation with no impact on fuel economy during normal driving. Installation is described as quick and plug-and-play. The Group 10 JB4 is designed for specific Volkswagen models, including the 2017-2021 VW Jetta 1.4T TSI and the 2019-2022 Golf 1.4T TSI. It requires a minimum of 91 octane fuel for performance gains. The unit is not VIN locked and is fully removable, allowing it to be swapped between vehicles or resold. It comes with a billet aluminum enclosure, is designed and assembled in the USA, and includes a 5-year warranty.
