I'm sure it's a bit of both.
Partially detuned to allow for the CP in a couple years.
A gearing comparison would help to compare the two graphs. The high revs and apparent lack of regard for fuel economy allowed the e92 M3 to have aggressive gearing… which made effective use of the available trq.
IIRC the ratios are published for the M4, does anyone know the percent difference in gearing between the old/new model? I'm too busy to look it up at the moment.
Keep in mind that if the new motor makes 20% more trq at a given rpm point but has 10% taller gearing half the trq delta is offset.
