Description
The Burger Tuning JB4 is the ultimate plug & play performance upgrade for the 2023+ Nissan Z 3.0L twin-turbo, delivering gains of up to 100 wheel horsepower and 120 lb-ft of torque on a stock car with pump gas.
This advanced tuner works with your factory DME/ECU to remap boost, timing, and fueling for optimal performance while maintaining factory-like smoothness and drivability. By manipulating ECU boost control signals—while leaving manifold boost reference intact—the JB4 ensures your ECU can properly manage timing and fueling for safe, reliable power increases.
Equipped with a 64MHz processor sampling sensors 1000 times per second, the JB4 provides ultra-fast, precise control. OBDII CANbus integration allows for advanced safety features, boost-by-gear tuning, data logging, and on-the-fly map switching.
Higher octane fuel or ethanol blends unlock even greater gains, making this the most capable tuning solution available for the new Nissan Z.

What is a JB4?
The JB4 is the world’s leading plug & play turbo tuning system, designed to deliver maximum performance with factory-like reliability. Unlike basic piggyback chips, the JB4 integrates with the vehicle’s CANbus system for dynamic tuning and enhanced safety.
With Bluetooth connectivity (via optional JB4 Mobile or JB4PRO adapters), you can view live gauges, log runs, adjust settings, and install free firmware updates as Burger Motorsports releases new maps and features.
