I got an '08. I have been bugging my local dealer to do the update forever and they wouldnt do it. Ive complained about everything you can imagine with no luck. So finally i went to my service adviser and told him look, my car dynod at 320hp - my car is weak! All the 11s and 12 dyno 350hp+. Slipped him $60 and he said ok ill ipdate it for you.
Got my car back today, yes the dct shiftig feels slightly different. Seems theres a slight lag from when you press the peddle to the actual shift, but when it does shift- it seems to shifter hardwr/faster. The car feels like its got a little more torque on the low end but i cant tell untill i go back on the dyno.
The biggest surprise? My edc is stiffer now on full sport + setting. This is something i have bot read about on the forums so it was a total shock to me driving home. But man i am loving sport mode right now. Feels like i got new shocks all around!!
