This could also be a corrupted file issue as well. I have experienced this first hand where after I put a first tune on a car, the lambse (commanded lambda) was showing 1.0 on the log when in fact nowhere in the calibration I commanded stoich for WOT fueling. This is a perfect example why datalogging is so important, issues like these could be prevented and caught early. I give credit to all of the mail order tuners out there, I purposely refuse to mail order tune a car due to Not knowing if the end user is logging properly and also not knowing exactly what the car is doing or feels like. To the OP I'm sorry to hear about this unfortunate situation. I hope you get it fixed up soon.
