I'm not a tuning expert and honestly have no idea how to change the tune on a FI car.

DFCO should be turned off on my car per my tune. I may try and switch out my O2 sensors again with a different brand to see if that helps. My car looks to try and really richen up the mixture on the left side of the engine. I'm wondering if it is loading up on fuel and thats why it hesitates when tipping in the throttle again.
