They couldn't wring a good lap out of it. Is that transmission literally the same part number as the one for the M3, or a "me too" version with different software and friction points?
I believe the M3 DCT is rated differently and would be a different part number. I can check penskeparts or realoem, but I do remember reading that they were different units. There are already upgraded parts for these DCT units; I remember seeing an article in Roundel with a supercharged DCT unit had upgraded parts.
