Installed today! Went pretty smooth. I wanted to let others know who may be in the same boat as me (MacBook Air user), that I had no troubles using the free Windows 8 Preview OS via Parallels software. Just double clicked the driver app that comes with the JB3 software (found on n54tech website), after that just found what the com number was and everything was smooth sailing from there.
Got out and drove it a bit. It's 32 degrees here so i never mashed it off the line, but i could definitely tell a difference. Looking forward to the day we have nice weather again and the car has fully adapted to the tune!
