SciFrog:

 I would hope a 997.2 TTS PDK would kill any stage 2 tuner job, straight line and track performance...

Good luck beating my CG544 Stage II in a straight line or around a track!

CG544 SportsAuto results:

If a Turbo S can achieve this even with PDK (at least 30kg heavier) then fair play to Porsche. 

The aftermarket kits do have the advantage of swapping the exhaust from a 600 cell to a 200 or even 100 cell, meaning much less back pressure and less lag.  Porsche can't do this as they have emissions standards to achieve.

So to beat a Stage II then Porsche's only option is to make the car much lighter IMHO or put in more than 550bhp.
