In this original thread on m3post (here), the discussion started with a comparision of the stock 3.85 final drive and the new Dinan 4.10 final drive for the 6MT. Soon that discussion morphed into a general comparison between 6MT and DCT and all combinations of final drive ratios.

An ECU upgrade affects a broad range of motor performance. Therefore comparing before and after results cannot be summed up by a single number. Max HP and max toque will not be enough; we need to look at the entire graph of performance over the broad RPM range.
