So are you still having the sputtering issue at launch? Bad idle? Just wondering if those O2 values were with the issue present or not.

I don't think a Bosch O2 sensor is an upgrade, but that is just my opinion. I would only use Toyota or Denso for the O2 sensors, and an improper air/fuel mixture seems like it would explain the OP's symptoms. Just a thought.
