I've had the DCT software on my E90 M3 for a few weeks now, and it's truly a night and day difference. The shifts are so much crisper, quicker, and smoother; especially the downshift from 3rd to 2nd. I'll post up a more in-depth review when I have a chance to get some footage of it in action
Props to BPM Sport and Mike Benvo for providing yet another amazing software for the E9X M3. Can't wait to get my Stage 2 Engine Software
