Weird noise after 4 speed install

I don't know guys. I'm ready to throw in the towel. I tried all the above, checked the plugs, rotor, wires, cap, rockers, etc. Nothing is out of the sorts.

No changes madee it any better, except increasing the idle past 1100 RPM. Doing that smoothed it out.
I even sent a datalog to a guy who does remote tuning and we moved a few things, but no change. He thinks it's something else, besides the efi.
