Did you have chain slap or anything else associated with it?
Got 99 problems and my Gen 1 is 1

If you look at you first data chart and compare the misfired cylinders to the firing order you will find your answer.
It shows every other cylinder is misfiring.

Okay, so I guess this is “solved,” and the first shop was right after all.
I drove two more Gen 1s today and they both had the same shaking shuddering idle mine does. I only got to hook Forscan up to one and it also produced some minor misfires, so that checks out to be “normal” as well and is why ford has a threshold before it sets off a light. One only had 30k miles and was a 2014, one had 88k and was a 2011. I guess it is truly the cam profile of the 6.2 specific to the raptor. It’s the only difference between our 6.2 and the 6.2 in super duty.
I will be looking to a tuner to raise the idle a little so it doesn’t dip so harshly as I’m just not comfortable with it.
I can definitely live with the shake, I just thought something was wrong with the truck, but lesson learned!
I will update this thread if it turns into anything else as I’m still getting a weird occasional pop from the driver side exhaust that makes me think it’s running too rich. But anyway, thanks everyone for the suggestions and advice!

The first thing I noticed was that studder or shake in the seat and floorboard at idle when I test drove my used 95k mile 2014. Among many other things it was my biggest concern after reading about valve spring failures. I had 5 days to return the truck for a 100% refund so during that time I took it to a 20year ford mechanic who now runs his own successful shop. Scanner like you said showed nada. Mechanic sat in the truck and also acknowledged what feels like a misfire-studder. However he looked me in the eye and said, "sounds normal to me". On the way out he agreed a warranty would be a good idea for the transmission while he had another 6.2 transmission replacement in the bay next to mine. I bought a warranty thru my credit union but now that I have gotten used to the idle I seriously consider canceling it and using the money for the new cams, springs and braces from livernois. I recently put a tune from 5star in so I will check the idle issue again. I've gotten used to it and have to tell my brain to let it go. I appreciate all the troubleshooting and posts you made. It's nice when someone else checks some boxes when your own list is already long asf!
