Burger Motorsports JB4 Performance tuner with wireless connect kit already installed. In great condition.
The JB4 is the most advanced and highly featured tuning system available for your B58 and B48 vehicle. Power gains are up to 80hp to the wheels (100hp 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, E85 mixtures, and larger turbos are even higher.
This was on my 2021 BMW M440i coupe
