I forgot to add a note about the clutch install... someone just asked me by PM and reminded me.

About 30 minutes in driving, the check engine light came on and the car ran really rough. I remembered someone on here, I think Process, mentioned having to do a crank relearn after swapping the flywheel or this would happen. I have to assume this is because the crank trigger is sandwiched between the flywheel and crank, and its a little loose, and chances are, after reinstalling, it will be off by at least a few minutes (60ths of a degree) or maybe an entire degree I dont know didnt really study it much.

I turned the car off for 10 seconds and started it back up and the CEL was off and the car ran normal. I took it to my dyno shop who had a SCT x4 and did the crank relearn (didnt have to "marry it"), and that seemed to have resolved it, as probably 300 or more miles later, I have not had this come back.

ALSO, today I got a CEL for the cats. Efficiency below threshold is what I think it said. I just had a Innovate OT2 for my iphone in the glove box and plugged it in real quick to verify it wasnt another crank trigger issue and I saw that it was the cats. I cleared it and went on with my day.

I can safely assume that this code will be constantly coming and going until I get a custom tune. For me, this is not a problem as I can easily reset it in 30 seconds while driving. But for some, this could be a fair complaint about running LTH. With a custom tune, I am positive they could turn off this DTC, but at least here in Illinois, turning off DTCs will fail you at emissions if it results in your OBD system stating "system not ready / unavailable". That is what happens when we turn off DTCs in my Nissan projects, not sure if the Ford ECU does the same but I bet it does.

This seems to be happening quite a bit. Are these stock clutches just garbage?

I think it's the 650whp+ and 500wtq+ that are crushing stock clutches.
