I continue to scratch my head about this N54 "power". The 2014+ EWG N55 in the M235 makes around 310whp/330wtq stock and the M2 N55 makes around 330whp/370wtq (Dynojet numbers). Even better, the power peaks at 6200rpms and holds 90%+ of that power to 6700rpms. Show me a stock N54 that makes that sort of power or doesn't lose a ton power after 5500rpms. In tuned form (pump gas or ethanol) and assuming you don't swap out turbos, the EWG N55s tends to make a little more HP, more TQ, and it's power band is wider. In general, making for a quicker and faster car.
Never seen a stock N55 hold power up high. This is base to base, you should see similar comparisons to the 1M vs M2 non comp curves too. The S55 and S58 clearly don't have these shortcomings.
