I had read that M550i does not require break-in as the engine is broken in prior to installation. Experts please advise....
Owner manual says 1,200 miles. It says don't push past 4,000 rpm for first 1,200 miles, do NOT slam the pedal all the way. I also think it states to not go over 90 MPH.

Once you hit 1,200 miles, you can slowly go higher with RPMS
After looking through the owner manual again on the M550, my numbers that I gave in the earlier post were off by a little bit.

Took a picture of it!
