If they have been turned off for sure in the tune they will eventually quit tripping the light. They do into the historical memory on the ECM, once there they take several key cycles to register they are cleared up.

Now whats throwing me off is i did the full LT catless and catless x pipe kit then did the tune and it still turned off the bank 1 sensor 2 codes but not the bank 2 sensor 2. Thats whats confusing me.
