I would always have far more faith in the factory offering than a aftermarket tune offering, no matter how good or respected the outfit was.
Oh and I don't know how many times I have brought this up but I agree, what ever people's opinions are about the new direction that M-Division are taking with their engines it is hard not to get a little bit shell shocked when you consider just how quick the X6M is and then think that this engine is going into the new M5 with even more power and a huge weight reduction.
