Back to the dealer again today to re-install the Stage 2. I watched the computer as it did the download and everything appeared to go smoothly. I drove the car and it “felt” great and if I were a betting man, I would say the software is installed. However, since I convinced myself that it was installed last time and it wasn’t, I am heading back to the track on Thursday to find out for sure.
100% BMW. Don't settle for cheap imitations.
