I have the above truck and when I accelerate moderately to hard, or when the car is more heavily loaded or going up a hill, I get a feeling of stuttering. I'm familiar with the feel of fouled plugs and its more subtle than that. It's almost like a very slight slipping sensation in the drive line, but by no means a flaring in the transmission and no rapid increase in revs like with a slipping transmission. It's just an annoying very quick stuttering while under heavier acceleration load. I have changed the plugs but so far no cure. Any ideas? Coils? Transfer case issues? Thanks for your thoughts.

I have a 13 gts too and had a similar what I would describe as more of a miss on acceleration when I first got the car. Turns out Porsche was having an issue with faulty crank sensors. They replaced all of mine and has been flawless for the last 70K. May be worth a check

Your symptoms are hinting at transfer case problems. Do a search on the subject. I'd suggest changing the fluid with the latest Porsche fluid. So far 100% of the cars that have had the fluid changed, where they had a problem, have experienced improvement. It's about the simplest service to do.
