There is really no rocket science required to determine how your transmission line has to be spaced to get the max out of it in acceleration, this is basic setup theory of the early times of the Ford T actually.
Take note, this is only gear 1, 2 and maybe 3 and therefore it is not in contradiction with an efficient, fuel saving drive line set up either. Certainly not when you have 8 gears at hand like an M550d.

The 125d has maximum power at 4400rpm, then power starts to drop as the revs get higher, thats just the way diesel works. It's the same story with the M50d engine, It has maximum power from 4000 - 4400rpm.
