Surging/Pulsing
I haven't driven the Targa much since buying it, but during my infrequent outings, I've noticed a mild pulsing/surging on acceleration, and while cruising. It's kind of like a mild speeding up and slowing down effect.
I've also noticed that over the past 3 months or so, it's gotten quite a bit "rougher" during a cold start. DME relay? O2 Sensor? AFM? Thanks!

Not positive but I think this can be traced to the O2 sensor. I had some other symptoms, erratic idle after warmed up, and was told by the board replace the O2 sensor. I did this and I no longer have the mild surging during steady highway driving. Could have been a coincidence though.
