System too lean

I have a 2006 mustang v6 with the 91 octane tune from the DiabloSport predator tuner. My check engine light is on and has many O2 sensor signals. And has a P1074 code. My question is do I have to change the oxygen sensors or take it to a dyno? I uploaded the codes on a picture.

You seem to have several O2 sensor issues. I would say the vehicle has an issue that needs to be addressed first.
