It delivers substantial horsepower and torque gains, with claims of up to 80hp to the wheels on stock BMW models and up to 100hp and 100tq to the wheels on stock vehicles for the N54 engine.\n\nThe JB4 offers advanced features, including multiple performance maps that can be adjusted on-the-fly from the driver's seat, a stock bypass map, valet mode, support for ethanol fuel (E85) and water\/methanol injection, and an auto-tuning map that continuously adjusts to your vehicle's current conditions and modifications. It also includes features like optional in-dash gauges, a programmable shift light, and torque limiting for launches.\n\nThis tuner is designed to grow with your vehicle, providing a suitable performance mix whether you're running a 100% OEM car or a heavily modified one. It is compatible with all ECU versions and transmission types, including DCT transmissions, and runs as smoothly as stock during normal driving. For enhanced data analysis and control, the JB4 can wirelessly connect to iOS and Android devices via the JB4 Mobile connect kit or to a Windows laptop with the BMS data cable. The JB4 system is not VIN-locked and is fully removable.\n\nFitment is specifically for various BMW 1 Series (E82\/E88 135i, 1M), 3 Series (E90\/E91\/E92\/E93 335i\/335xi, 335is), 5 Series (E60\/E61 535i\/535xi), X Series (E71 X6 xDrive35i), and Z Series (E89 Z4 sDrive35i\/35is) models equipped with the N54 3.0L engine.
