Description
The JB4 Performance Tuner for the 2026+ Dodge Charger Scat Pack SixPack 3.0L I6 Hurricane Twin Turbo is the most advanced plug-and-play tuning system available for Dodge's latest high-performance twin-turbocharged platform. Designed to deliver substantial power gains while retaining factory drivability, safety systems, and ECU integrity, the JB4 provides up to 100 wheel horsepower and 130 wheel torque on an otherwise stock vehicle running premium pump fuel.
The JB4 connects directly between the vehicle's sensors and ECU, allowing it to actively adjust boost, timing, air-fuel ratios, and fuel trims in real time. Unlike conventional performance chips, the JB4 utilizes advanced CANbus integration, fuel and spark control, real-time monitoring, and sophisticated processing capabilities to provide safe, smooth, and highly effective performance gains.
With support for multiple performance maps, ethanol blending, boost-by-gear control, anti-lag functionality, wireless Bluetooth connectivity, data logging, code reading, and firmware updates, the JB4 offers unmatched tuning flexibility for both daily driving and performance enthusiasts.
