Updating code in car
Can somebody explain to me what the benefits are for upgrading the code/firware/240e software (not sure what the exact term is). I have a 02/08 build and it has never been done. Highly considering it, but wasn't sure what all it did to the car and figured it would be good to know before I spend the money... Any help is appreicated. I've tried searching, but can't land on much to say what all it does. I have seen some claim you get more power from doing this, but I figure that is just speculation.
