TGS N55 PPK Install
I had Joe from TGS install PPK on my 2011 N55 135i last night. After about 1 hour of time, most of which was getting the laptop setup with the software and PPK files, Joe was done and I rolled the car out for a quick test drive.
The PPK certainly improved the throttle lag with my DCT. Just in "D" there is not much difference from pre-PPK that I can tell, but I rarely drive in "D". With the sport button on (how I normally drive) there are some extra burbles and pops and it just feels a little more "responsive". If you put the shifter over and put it in S-mode the burbles on deceleration are crazy (good).
I would be unhappy with the dealer cost of the PPK but this was a great update from TGS - well worth the cost of the coding. I am computer handy and I wouldn't be able to do what Joe did again. Props to them for the update!
