Was just going to move it over to the other side of the garage but backing out it was acting like it was back to normal so I took it around the block and everything from idle to a gentle pull was great. Even idled great for 5 minutes when I got back.

So WTF is this thing just messing with me? I do have before and after logs if anyone wants to look at them to help me figure out what is going on.

Thanks for the winning suggestion JLAudio11.

So when I first started tuning my car after adding the turbos and thus changing the inlet pipe and maf setup I accidentally induced a situation where I had it so rich it was reading lean. I had to take a step back and say there’s no way this is correct and somewhat start over. I think something like this is what happened to you and me. It’s so rich it reads lean and the stft just keep trying to add thinking it’s lean and prolonging the situation. It’s why when I saw crazy high stft my reaction was to reset it. Why it goes rich/shows lean I’m not sure. I’m thinking a weird reading on startup is what starts the process and it can never get out of it. Somebody else might have a better idea but that’s just what I’ve seen in my experience.
