Not true... how can you possibly take one non-scientific comparison and make this statement. First, who knows if the tune was properly implemented on his car. Second, there is a TON of evidence that these tunes add measurable and real power. More power = faster, period. You can't ignore the wide body of non-subjective evidence and rely on one member's bad experience. You have already convinced yourself that tunes are not worthwhile, in your opinion, and you want to take every piece of evidence, good or bad, to prove your opinion but you are clearly ignoring the vast majority of evidence (dynos, the Evolve video) to the contrary.
People who know FAR more about this than you and I would NOT agree than the M3 is tuned "optimally" from the factory. It is a compromise tune because the vehicle has to meet a wide range of needs.

Although this may be true, that does NOT mean the BMW engineers are programming the engines for maximum potential output/power. They are leaving large tolerances and making compromises for the broader market. Could they "tune" more power from factory? Yes. Could then maybe even "tune" more power than the independent shops? Maybe, yes. But just because they could does not mean they did... cause they didn't.
