if the company knows what there doing then it can be raised safely. i have had there tunes on my past 3 M cars and never a problem and that is over 100k miles of driving
i also never had one problem at any BMW dealer with it and they all knew i had the Dinan software in there and on this current one and they still warrantied my car for anything it needed
but yes i agree it is more universal to work on any M3 versus a custom tune etc

One could argue that raising the rev limit to 8600rpm is potentially more dangerous than any other tuning change that could be made - it certainly raises the possibility of the tune being detected (most conservative folk probably wouldn't want that).
