Surges when cruising at 55 plus o2 sensors

Ok so I Have a 2014 Camaro ss L99. When cruising at 55mph I noticed that it was always adjusting then kicking in causing a surging feeling. Very irritating when cruising at that speed. Never enough to Change the speed just enough to feel it. So I also ended up getting a P015B code. Had the O2 sensor replaced. Bank1 sensor 1. Anyway didn't fix the issue now I have occasional P015b and P015D codes. Bank 1 sensor 1 and bank 2 sensor 1 codes. My car also has K&N cold air intake and muffler deletes. Which was on when I bought the car used. So Since I got the code for the sensor that I just replaced I was wondering if It might be because the car needed to be tuned and not actually an issue with the a bad sensor. Also I used a OBD Scan tool today and from what I could tell all the sensors are working properly.

Start with a tune, even an off the shelf SCT tune should be an improvement.
