Looking for input on my engine vibration issue.

I am sure you have already done this and run the diagnostics on the PF4 tablet, I had injector come off on my PF4 which was causing your symptoms (#6 cylinder). Popped connector back on and all was good. Have you also checked around your spark plugs to make sure your boots are not burned and possibly grounding out on the header?

Actually, I haven't run the diags. I forgot about it since splitting the engine/transmission is so much easier.
I did verify good burn at all cylinders with plug pics sent to BP.

I am going to make a video using a plastic cup of water on the air cleaner and the RPM displayed next to it on my tablet.
Also do a compression check.

Just for giggles check your firing order and make sure you don't have a couple wires crossed.
