The N54 will heatsoak on a hot, humid day. I have run my tuned 135i N54 on tracks in the south (Georgia, SC) and on my final couple laps each session I can feel a slight loss of power. Generally it isn't enough of a loss to be to concerned with during relatively short HPDE sessions. If I was a club racer (I suspect the OP does multiple trackdays or is closer to being a club racer) then I would be concerned about that loss over long track sessions. People you don't have to defend the 1M, it is probably a great car, but it is not the giant killer the fan-boys think it may be.
