Identical flash or tune should yield identical results/numbers. The tune adjusts parameters to a certain level and what level those parameters were at before the tune are irrelevant.
If map 5 is 14 psi then its 14 psi in either car, one car may have started at 9 and the other at 12 but they will both be at 14. It is not like a bolt on that adds X hp to baseline.
What BMW changed on the 1M (as far as software changes go) ate up into the space that the tune works in.
