A bust

For all concerned about the Jb3. I had problems with mine. 2 different installers, 2 different juiceboxes... Drivetrain malfunction. But when the error message was off. The x3 was very fast. I was so happy with it. It was the perfect SAV, 0-60 5 seconds flat. Too bad for the error messages, which by the way slowed the car down substantially. I had to sell the unit and go back to stock. Oh and Terry and I had several email convos. We couldn't troubleshoot it.
