Is this normal for a Tiptronic trans?
 

After I get done with a very spirited drive (I mean pushing my Tip as hard as I can). When I get home the console shifter is harder to move then normal.

Durametric doesn't show any fault codes on the trans.

Any of you other Tip owners experience this?

I've not noticed this. Maybe I'm not trying hard enough! ;)

When was the last time you had the TIP serviced?

Could need a fluid and Filter change. But have it done right it's very important.

Normal driving, the shifter moves with ease, but after putting the car through it's paces, the shifter is harder to move.

I've only experienced this twice but it was after the car had been parked for days, not after driving it hard. Without actually experiencing what you are talking about it is hard to comment about it. Perhaps taking it to a Porsche mechanic, when it is doing what you are saying it does, would be advisable.
