Description
Maximize the performance of your 2023+ Nissan Z 3.0T with the JB4 Performance Tuner—the most advanced plug-and-play tuning system on the market. Developed by Burger Motorsports (BMS), the JB4 seamlessly connects to your engine’s sensors and CANbus system to safely increase boost, remap timing, and adjust fueling—without the need for an ECU flash.
Unmatched Power & Efficiency
Delivering dyno-proven gains of up to +100 horsepower and +120 lb-ft of torque to the wheels on a stock vehicle, the JB4 dramatically improves acceleration, 0-60 times, and 1/4 mile performance. The JB4 works with your factory DME to maintain safe fuel trims and ignition timing, resulting in factory-like drivability with significantly more power under throttle.

Built to Last, Made in the USA
