I think the answer is a resounding NO. Short of getting a manual trasmission, or an M for that matter, if you want your Step to shift faster, get the Dinan tranny software. Note however, that in Manual-mode, the Dinan software really isn't noticable. It's best in Sport-mode. For more on this, do a search :thumbup:
so when you retro fit this, does this shift as fast as in the M3?
