Good point. I wasn't ragging on the 335is, but now I wonder if a PPK'd early N54 135i would match the 335is numbers.

Which brings me to my question, what has changed in the N54 over the years?

This old dyno testing shows there is a huge difference between the older 335i N54, newer N55 and the 335is with the 335is beating the old N54 in all respects:

Even the torque curve of the 335is doesn't compare to the early or late 335i.

So I really question if they drove in "D" or used manual. If they didn't have sport on then maybe DSC was intervening?
