Product Details

Not for sale or use in the state of California.

The JB4 is the most advanced and highly featured tuning system available for your B58 and B48 vehicle. Power gains are up to 60hp to the wheels (80hp crank) on a completely stock car on pump gas for a B58 and up to 40hp to the wheels (55hp crank) for a B48, gains with bolt-on parts, higher octane, and larger turbos are even higher.

The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with 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, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.

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 for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter. The JB4 automatically detects between the B46, B48, and B58 models at boot up making installation and setup a snap.

Note for 2018+ G chassis vehicles with the digital dash layout, Burger Motorsports have not yet added in the JB4 commands to allow in-dash control but will provide those via a free firmware update once developed. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.
