The Burger Tuning JB4 is a plug-and-play performance tuner designed to increase the power and performance of your Kia Stinger. This device connects to your vehicle's sensors and manipulates their signals to achieve significant gains. Developed and made in the USA, the JB4 comes with a 5-year warranty for peace of mind. The JB4 tuner is compatible with various fuel types, offering dedicated maps for 91 octane, 93 octane, and E85. It allows for smartphone connectivity, enabling users to adjust tuning settings and monitor performance data. Additionally, the JB4 can read and clear fault codes, providing diagnostic capabilities. Installation is a quick plug-and-play process, and the unit is not locked to a specific VIN. The JB4 is compatible with all driving modes and includes an OBD II cable. As of June 12th, 2026, it also includes the JB4 Pro Bluetooth Adapter for wireless connection to iOS and Android devices, allowing for advanced data analysis, map changes, and firmware updates via a free mobile app. An upgraded spark plug set (HKS) is required for use with the JB4 tune; customers must select the correct engine option (2.0T, 2.5T, or 3.3T) to ensure they receive the appropriate plugs, as using OEM plugs may lead to issues. This product cannot be sold or used in California.
