Yeah, the sensor fault DTC processor was throwing you into an extra rich limp mode just in case you had E85 in the tank. It is written into the tune but only addressable by disabling the DTC processors. Glad you got it sorted out.

See what the NBs look like in the new logs too. Didn't seem like they were as rich as the WB was reading in the previous logs.

 

Here's a log I took today. Still seems rich to me. I wonder if the sensor has been goofy for a long time and was throwing off my afr at throttle. Idle and cruise seem ok.
