it makes sense n it feels like my car is not running properly due to the fact that i followed instuctions on the manual.ive heard a lot of ppl say if you run ur car from the beginning ur car is faster.maybe i was too careful in the beginning.
I have a really hard time believing that. I'm not 100% sure what the break-in period is all about, but supposedly, it gets the valves "seated" (whatever that is) and gets all the internal surfaces bonded with a thin film of semipermanent oil molecules. I can't imagine high revs will help the process; high revs put a lot of stress on internal parts that don't have a good "thin film" coating, and would put a lot of pressure on valves that haven't "seated" yet. I think pushing an engine hard early on will lead to premature wear.
