Anyone do 997.2 PDK update/upgrade? Experience, thoughts?? I have an 09c4s and would appreciate feedback

 

It was done at the same time I had the PDK clutch oil changed. The update definitely softened the shift firmness Sport and especially Sport Plus. Personally, I preferred it before. I liked the kick in the pants that you got when using manual shifting in Sport Plus on days when I felt especially rowdy. In normal driving I guess it is a little more livable. Unfortunately it doesn't eliminate the sudden slow-down with the automatic downshift from 2nd to 1st that happens just before a stop; it's hard to say if it affected that much at all.
