Just gotta keep spreading the word, the JuiceBox tunes seem so primitive compared to the COBB Access Port tune. Why struggle installing/uninstalling physical parts in your car when you can spend 15 min or so flashing it through the OBDII port and have the ability to change maps on the fly...including a valet mode....totally undetectable by BMW too since you literally flash it back to stock in approx 15 min.
Great looking 1, and enjoy your n54 engine. I know I do and my car weights a ton more.
