Your WB02 should not be your reference, that should be the main one you look at. .94 off the front O2 doesn't tell you anything because it is out of its normal operating range. It is made to sense a narrow band around 14.7:1 AFR. Hence the name narrow band O2. You wideband is made to sense from 9.0:1 to 20.0:1 usually. I don't even use my narrow band because it is worthless.

As for the inaccuracies, some people on the WB02 list (techedge) found that the swirling air coming out of a turbo could cause problems with the accuracy of the 02. You also do not want the 02 sensor to be above 1200 degrees, which it may get to near that point that close to the turbo. If yours is working, then that is fine. It is just not in the recommended location.

I also don't understand why you don't tune on the street at all. Where do you drive? Then that is where I would tune. I also don't understand the problem with getting AFR's from the WB02. You shouldn't be over 11.5:1 on pump gas.
