I would think that if the ECu sees 17:1 at WOT it would probably throw a check engine light for not being able to hit the targets by ~5 points. What device are you seeing the 17:1 AFR through again? Are you seeing 17 in the UpRev datalogs?

If your WB sensor isnt working right then it would likely be imposible for anybody to give you a good E-Tune.

I think your setup is bad. Also, UpRev would not likely tune against your external sensor unless you ask them to. They'd tune based on what the Cipher datalogs show.
