I installed the TPC DSC module in my wife's 2014 Cayman S a few weeks ago. The handling has improved, less harshness in sport mode on the street, feels better planted in traffic circles (we have a lot of them in our area, very useful for testing fast transitions at moderate speeds). We won't be able to make a full assessment of the improvements until we get the winter tires off and the car on a track (1st DE - April-02 at Limerock).

I decided to do my first Porsche DIY for this installation. If you have the skills to remove the engine cover, then you are ready to do this DIY.

Feedback is always welcome. It would be useful if this was placed in a DIY section or made a STICKY if the moderator agrees.
