OK, I just bought a 2002 540ia sport. I drove it to Havasu from So Cal last week-end. twice I decided to see where the governer was set. Both times it went past the 155 mark on the spedo looking like 158. It was a slight declined and perfectly straight raod. Has it been reprogrammed to eliminate the limitation and if so How can I find out? you wouldn't beleive how smooth it was.
