You mean the guys who modded their E55's dyno'd with higher numbers. I had an E55 and was hanging out in the E55 forum, there was no proof that hard break-in produces higher HP.

Happy Super Bowl Sunday....
Sorry guys, I'm getting out of hand. Cheers.

I ABSOLUTELY AGREE with Norb. Changing oil at 50 miles is STUPID. You are adding more friction reducing compounds found in all motor oil. Although not a believer in the break it in easy and then run it hard. You can create issues by needlessly changing oil. This run in discussion is ponderous at best. Drive your car as YOU see fit. If AMG was absolutely convinced the occasional "full throttle " blasts were detrimental they could have easily modified the ecu to FORCE a SPECIFIC break in.

Stupid question, but:
1.) If choosing the break-in method using the "go nuts" way, does it have to be done in M mode? Can you do it in S mode?
2.) If choosing the break-in method using the "go-easy" way, does this mean never to rev the engine beyond 4500rpm until 1000-1500 miles?

If a "run-in" or "break-in" period was truly of absolutley no value then why would the AMG engineers even bother mentioning it? And if AMG is keen on producing the most HP out of a motor then why would they then recommend a procedure that some have suggested will actually DECREASE the output to a lesser number then the car is rated? That seems like a counterproductive move in a market segment where more BHP is considered a demi-god.
Plain and simple, it is critical to run the car at different speeds for several hundred miles to make sure that the cylinders, engine bearings and other parts wear evenly. By the stupid sticker on the windshield and the even more stupid words in the owners manual, the engineers have accomplished what they want, by default, and that is that they probably do make each and every one of us VARY the way we drive the cars for at least a few hundred miles. Yes it says do this for 1,000 miles (I think mine had a approximate symbol near the 1,000 BTW) and of course we all probably went above 4,500 RPM a couple of times here or there but that damn "run-in" thought process then made us back off, vary the speed a little, hold the transmission in second at say 3,200 RPM a bit then shift it 3rd and hold it again maybe. Admit it, you are doing it now or did it when you got your car in some shape way or form. All this does is VARY the speeds of the engine, tranny, differential so that the best possible meshing between all components occurs which cannot be duplicated on a dyno and David Winterhoff (who built my motor) certainly didn't have time himself to drive even a few hundred KM in my car and then the next one he built.
By the way, anyone else have his name on their motor - I think he did a fantastic job thus far
