The dealer said the new update just came out on Sunday. I think the 12.07 part of 12.07.508 indicates the update was made on December 7th.

My car was delivered on 1/28/11 and the program I was running was 10.09.511. I'm guessing the old program was from October 9th 2010.

I don't think you need an update unless you are running 2010 software.

I can't feel the 10 or 20 horsepower gain that some claim. A small hp gain would be hard to notice in a car like this. The change in drive-ability is drastically better and that is what you will notice.

However, I do believe that the car does have more horsepower. The BMW tuners have had more time to update their programs and make them better.
