Description
Unleash your Infiniti’s hidden power with the Burger Tuning JB4 Performance Tuner for the Q50, Q60, and QX30 2.0T. This advanced plug-and-play system delivers up to 40HP and 40TQ to the wheels on a stock vehicle—no ECU flash required.
The JB4 connects to two easily accessible sensors under the hood and works with your factory ECU to remap boost, timing, and fueling for maximum performance with smooth, stock-like drivability. Thanks to its 64MHz processor and high-speed sampling, the JB4 ensures responsive, reliable, and repeatable performance.
Boost levels are user-adjustable with the optional BMS data cable, and installation takes under a minute. The JB4 can be used standalone or in combination with a flash map for even more gains.
