I ran the dealership fill down to fumes and have run nothing but 93 Octane for every fill-up.

To be clearer about the idle, it is subtle - it remains at 500, but every second or so it almost sounds like it is skipping a cylinder. It actually sounds like a classic camaro on the 1/4 mile line with a slight miss, but should not be like that for a stock build. I actually think it makes the car sound mean. If not for the hesitation/bucking I would not have said a word - there are even other posts/thread here that talk about the LS3 and a "rough idle", but they do not mention the hesitation/bucking.

To be fair, I think my thread title is a little off - it should be "Dealership says it cannot troubleshoot car with the CAI" - regardless, it just seems like they took an easy out once they saw the CAI. Why not do a computer check and a cursory check of the main suspects, like timing, compression on each cylinder, etc.?
