B46/B48/B58 JB4
Ready to take your BMW B46/B48/B58 turbo to the next level?
How about up to 60hp to the wheels (80hp crank) on a completely stock car on pump gas for a B58 or up to 40hp to the wheels for a B48? The JB4 features a simple plug and play installation harness for easy installation and includes many features not found on any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in dash gauge displays for boost, 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. It automatically detects between the B48 and B58 models at boot up making installation and setup a snap.

Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but we strongly suggest the BMS DATA cable so you can load free software updates.
