The JB4 tuner installs between your car's sensors and its DME\/ECU and manipulates vehicle performance through these connections making your vehicle much faster. The JB4 separates itself from the competition with more advanced connection points and processing, including CANbus, fuel \u0026amp; spark control, Bluetooth connectivity, and a variety of innovative and advanced features. The system is not VIN-locked and can quickly be removed, swapped between cars, or resold later.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the JB4 a real tune?\u003c\/strong\u003e\u003cbr\u003eYes.
