I used D6 and dont really like it. Its notchy and shifts are sightly harsh. If i use M mode and shift @ WOT around 4k i can feel the notch of it disengaging and then re engaging the clutch. Its like a double clutch. No slipping, no noises, just TOO NOTCHY! However it could be the Alpina flash as I have never shifted that high with the factory TCU flash.
