Description
Unlock the true potential of your 2.5T SmartStream engine with the Burger Motorsports JB4 (V2) performance tuner for Kia, Hyundai, and Genesis vehicles. This advanced plug-and-play tuning system delivers impressive power gains of up to 65 horsepower and 80 lb-ft of torque to the wheels on a completely stock vehicle, all while maintaining factory safety systems and smooth drivability.
The JB4 system connects directly to key engine sensors and works alongside your factory ECU to optimize boost, ignition timing, and fueling. Unlike basic tuning chips, the JB4 features full CANbus integration, allowing it to monitor and adjust performance in real time using critical data such as throttle position, gear, engine speed, air/fuel ratio, ignition timing, fuel trims, and knock detection. This ensures consistent, safe, and optimized performance under all driving conditions.
Designed for enthusiasts who want both power and control, the JB4 includes multiple performance maps for various fuel types including 91 octane, 93 octane, and E85 blends. Map switching can be done on the fly, and the system includes advanced safety features that reduce boost until proper engine temperatures are reached and automatically lower performance if unsafe conditions are detected.
The included JB4 PRO Bluetooth module allows seamless wireless connection to your smartphone. Using the intuitive mobile app, you can monitor live engine data, log performance metrics, change maps, and update firmware with the latest performance enhancements—all from your iOS or Android device.
Installation is quick, fully reversible, and leaves no trace when removed, making it an ideal upgrade for both daily drivers and performance builds.
