I don't know the power range on the n55. But on my 6mt n54 I shift at 6200-6300 rpm to keep it in the power range.
Back when my car was stock I was able to pull 0.5-1 car length on a stock e92 m3 that a friend owned. Above 100 he started to pull away steadily.
So in that range I would think it would be a close race.
