My dealer offered the option to me but suggest that I should wait for potential options from more reliable tuners because the OEM PP is ridiculously overpriced.

I wasn't aware that the performance upgrade was available for the X3 at the dealer... does anyone know if this upgrade is available and if so, has anyone evaluated the performance?

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.
