Afaik I know my rev limit wasn't raised number one. And I happen to know two different techs at two different BMW dealers that said if a problem is serious enough BMW NA Reps can read your car and tell its been flashed so that is false. And if its not that serious then you're basically in the same boat as everyone else.
