Bms has a 435 pumping 414whp so correct me if I'm wrong but thats above 360bhp no?

Those BMS cars have more than just the tune and pump gas though, correct? Maybe I am wrong...
I understand the ECU argument - but we can also tell by the number of cars tuned that have N54s vs. N55s that there is a higher ceiling that is more easily achievable with the N54...at least that's the impression I have gotten from the board.
I am clearly not an expert - just commenting on what the general tone has been on the threads I have read.
