The Burger Motorsports JB4 Performance Tuner is a plug-and-play chip tuning system engineered to enhance the performance of turbocharged vehicles. It features advanced connection points that differentiate it from other tuning systems on the market. The JB4 provides on-the-fly map switching, allowing drivers to seamlessly transition between stock and performance maps. Key features include boost-by-gear control, which helps improve traction by managing boost levels according to the selected gear. For advanced users and those with heavily modified vehicles, the JB4PRO board is available, offering integrated Bluetooth connectivity and built-in ethanol sensor processing to eliminate the need for separate components. This tuner also has the capability to read and delete fault codes, providing diagnostic information. Safety is a consideration with the JB4 tuner, as it incorporates features like maintaining lower boost pressure until the engine's oil and water temperatures reach optimal levels. This helps protect the engine during initial startup and warm-up periods. The system is backed by a 5-year warranty, underscoring Burger Motorsports' confidence in its durability and performance.
