I stuck with what the manual said. There should be snipit regarding break in, but just keep RPMs below I believe it was 4k? Vary engine speed and try not to cruise at the same RPM for too long. All within the first 1k miles. After that you're free to drive it however you want. During my break in I did let it go past 4k but only for short bursts, and engine has held up perfectly fine. I'm currently at 70k miles.
