I'm no expert but if I understand what you are saying;
you had a wide band o2 sensor on it and it said you were at 14.7:1 stoichiometric ratio at idle and part throttle.
at wide open throttle the ratio was at 12.5
at 10:1 you ?hit? COT. Is "COT" Cat Over Temp?
the injector duty cycle is at 85%.
Sounds like you are going rich. but why?
Check out Schrodingers Box on you tube, he has videos on how to test everything out to find out why.

I do have a fuel pressure gauge and already checked that.
I'm pretty sure 12.5:1 is not too lean for WOT. As far as COT goes, it was being enabled while logging a run for the guy who did the tune for the car. It locks the AFR at 10:1 for a period of time to protect cats. He disabled it some how (it's an "item not defined" item in tunerpro and tuner cat because I can't access it.
The injectors go to 85% duty cycle at wot, high rpm when it's in the 12:x afr range, which if I wasn't data logging I probably wouldn't know.
BUT I really, really don't want to bring up the past too much. Most of that info I for one reason or another thought was necessary to provide....or not.
I someone were to look at a log file that I uploaded, or even better the datamaster log thats too big to upload, they would see that it's mainly idling from a cold start when ESC activates and stays activated--this was my question: any ideas why?
I have numerous log files where it never enables. I have files with some spark retard and it never enabled.
From what I understand it's supposed to enable after X amount of spark knock/detonation/pinging (whatever your preference is---spark happening too soon)
I'm so #@##%%ing sick of this @@@@ing car really.
