First step would be checking the fuel pressure. I know you've tried checking different widebands, but where is the sensor mounted, could there be an air leak near it? I suppose after that you need to consider getting your injectors tested.

The o2 sensor is located in the mid pipe about 1ft after the test pipe. There is a stock 02 sensor located at the same angle about 2 inches in front of it, I will try switching them to make sure that the stock 02 sensor is not blocking air to the wideband. Also would an exhaust leak matter at WOT, as far as getting accurate AFR readings.
I gotta find a fuel pressure gauge and then I can see whats what.

I know we don't go off narrowband O2 readings for good reason, but for what its worth yours is showing a higher voltage than mine is... yet my wideband says I'm running richer.

I don't think I have an exhaust leak, the car does not sound like, if there is a leak it would be very very tiny.
Don't bother looking at my 02 voltage, I have a non-fouler on the sensor so it does not throw a code.

Generally, the idea is simply to put in a sensor or gauge inline with the fuel line.
I don't have any experience with this fuel system but the concept is the same on all cars.
You can get T fitting and send one end to your sensor/gauge.

I suspect I may have an exhaust leak because my AFR at idle is 16 on the wideband. What is the 02 voltage supposed to be at idle?
I think a small leak may throw off my AFR readings slightly about 1.5 at idle and maybe .5 or so at WOT.
