Clear the codes, and see what comes back
You never mentioned Turbo or NA, how many miles? Dyno or synthetic oil?
You never said if you tried switching plugs at Nr 1 & 2
and looked for any subtle clues wet or dry? gap OK?
Do another compression test on a warm engine to be sure. It's
no big deal with stuff apart.

Maybe swap # 1 and 2 injector to verify the Nr 1 is OK?
Look in the harness socket for #1 injector, is it clean
If in doubt blow it out with compressed air or brake cleaner
and then put some dielectric silicone.

There's one other thing I forgot to mention. Look at all the ignition
stuff at night, See if you notice any corona around the wires or distributor
cap with the engine running. "New" doesn't rule out faulty.
