Any 2011 AT owners out there -- weird throttle response?

I bought the 2011 v6 AT against my better judgment. All along, one of my only stipulations was that the 'Stang be a MT. I was even willing to consider GTs in order to get the elusive MT since most V6 models seemed to come with AT. Well, I finally caved since I found the EXACT V6 model I wanted (silver, stone interior, premium, MCA package) except that it had AT. Ultimately, it meant my wife could drive it, though, since it wasn't a stick.

For the most part, I've enjoyed it. Living in ATL, an AT is very nice for when 85/75 becomes a parking lot. No more Texas 2-step to move 1 foot in traffic.

What I've noticed, though, is a weird throttle response where stepping on it has about a second or two disconnect between sending gas and getting any response from the engine. Maybe that's a bit of hyperbole, but it FEELS like a second or two between mashing the gas and moving.

Another thing I've noticed are some really weird shift points where sometimes coming out of a turn at low speed (around 15 mph or so) leads to a bit of a jolt as I guess the car maybe downshifts from 3rd to 2nd or 2nd to 1st?

Has anyone experienced these two things and have any sort of solution? I have thought about talking to the dealer, but I wanted to get some input first.

the newer stangs are drive by wire so there is no throttle cable, its probably how its programmed to work (throttle response wise)

So, is that something that could be "corrected" in a tune?

I think a tune should be able to change the shift points in an AT on top of netting you some power.

Yeah, I was just curious if that delay could be something happening with the ECU which could/would be adjusted with a tune. My amateur guess is that it's a fuel-saving countermeasure when someone punches it, and it's incorrectly applied in some circumstances as well as compounded by weird shift points or algorithms? for determining shift points. I need to do some "testing" though and see if I still experience that with Trac Control Off and Advance Trac Off.

I really know next to nothing about AT cars as I've owned a MT for all of my life until I bought this one.

I have the 2011 V6 auto and it hesitates when I stop and then proceed at light throttle from a stop sign. So far I am just living with it. But it really bothered me at first because It acted for a second like the engine cut off.
