Description
The Burger Tuning JB4 Performance Tuner is the ultimate plug-and-play solution for the 2016+ Infiniti Q50/Q60 3.0T. This advanced tuning module integrates with your factory DME to deliver smooth, reliable power increases while maintaining OEM-like drivability.
By attaching to just two easy-to-access engine sensors and tapping into the OBDII port for CANbus data, the JB4 modifies boost, timing, and fueling for maximum gains. Unlike flash tunes, the JB4 does not alter the ECU’s manifold boost reference—allowing the factory ECU to adjust timing and fueling correctly for higher boost levels.
On a Silver Sport model, expect up to +100whp and +120wtq depending on fuel quality. On a Red Sport, gains of 30–50whp are typical. Higher octane or E85 blends enable even greater boost targets for more power.
Compared to the Stage1 tuner, the JB4 adds advanced features like full data logging, boost-by-gear, AFR adjustment (with optional fuel wires), and on-the-fly map switching.
