Default AFRs staying the same no matter what load

Hey guys recently my AFRs been acting up. Starting the car in idle they stay around 15.0-15.8. As i proceed to accelerate and at WOT they still stay in that range. The car sounds to be running fine, and responsive.

Things already checked: Timing, VAC leaks, pinched hoses.

I tried in the tuning software to increase the fuel in the VE Table and it worked, i heard my car bog upon acceleration but the gauge still read 15.3. Is my AEM UEGO wideband messed up, or is it somewhere in my tune that is wrong.

Here are the tune and logs.

Yup it was the wideband. Traced the harness and found one wire was completely cut. Soldered it together and works fine now . Running rich so I have to re adjust the VE again
