Feels like shifting execration or RPMs has changed
 

I don't know how to describe it but I feel like I have noticed my 2014 CX-5 GT feels different or is shifting different. sometimes it doesn't accelerate as responsively as I think it should when going from a stop.. or I have noticed it's not shifting through gears when it should (eg staying in I guess 3rd for a bit too long). I dunno if its the computer, sky tech, something. Ive only had it a month, has 52k miles and all great maintenance records when I bought it. I am worried its the signs of a more serious issue. I had a 06 Mazda 3 before this and I know that if my battery got disconnected I had to let it idle for 20 min to relearn the engine. I did not have a power disconnect though.
