break in period on e63
IMHO no break in required just make sure it shifts smoothly and lets you get close to the red line w/o upshifting too quickly

On a serious note both methods can be argued back and forth. I believe in following the recommended engine break-in procedure just in a more aggressive manner.

Juice, I want to keep up with that car of yours. It's the test car for "first break ALL the rules.
I've always wondered......would a vehicle's "little black box" record the maximum revs on an engine? So once you took the car in for it's first oil change, would the tech be able to see what the maximum recorded RPM's were during the break in period? If so, and if you had warranty issues, I wonder if they'd void the warranty in an extreme case?
