I have experienced this. In my case, it was torque steering that kicked in. Squirrely is the right word.I'm generally a lighter foot person anyway. The first week or so the BS seemed like too much for me even if I kept the RPMs below 3K. Now I'll let it shift right around 3k (or maybe a touch higher) and it's fine. I did pass someone with frustration one day causing my wife to say "what the hell was that?!?" after I accelerated in the passing lane and the thing seemed almost to get squirrely.
