Burger Motorsports JB4 Tuner 22-24 WRX / 19-24 Ascent / 20-24 Legacy / 20-24 Outback XT

The JB4 is the most advanced and highly featured tuning system available for your 2022+ Subaru WRX 2.4L 4 cylinder turbo. Power gains are up to 50hp to the wheels (70hp crank) on a completely stock car on pump gas, gains with ethanol mixtures and bolt-on parts are even higher.

The JB4 features a simple plug & play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly map switching from your phone/tablet instead between factory and various performance maps, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, and much more. 
 
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit found here, or to your Windows laptop with the BMS data cable found here. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. A separate JB4 Mobile app purchase is also required.
