IMO, follow the recc'd break in mileage and rev limit, BUT do vary the speeds and rev ranges throughout the initial break in period...like one said, don't just cruise at 3000 revs for 1200 miles.....don't be timid to take it to 4k or 5K rpm's....
at least that what I've done with previous cars and doing with my current M3...I'm barely at 250 miles
