I have the surging problem and hesitation off idle; otherwise, the cars runs just fine.

I did 12-15-14 and didn't notice a performance difference. Unfortunately, the car is much quieter now (less pops and gurgles). Also, only fixed the hesitation for about a month and then came back. I'm pretty sure it was just the dct adaptation reset that accompanied the software update that fixed the hesitation initially and came back after adaptions were relearned. IMO, update is not worth the trouble.
