Swamp, thanks for your efforts. I am surprised that the differences between MT and DCT are not a little more pronounced.
I was fairly disappointed a few months ago to hear the DCT option had been nixed for the 1M. Although your calculations suggest marginal improvement with DCT, I still wonder if one's subjective impression of N54 power delivery would not be substantially better with a dual clutch setup given the seamless shifts affording fairly constant boost levels.
The N54 with the 6MT sometimes produces very noticeable 3rd-4th bog as you wait for boost to spool. Perhaps I am missing the optimal shift point, but it would be nice to avoid it altogether.
I haven't had the opportunity to drive a 335is with DCT, and that would probably provide the closest approximation of what a DCT 1M would have been like.
