As a reminder from the OP, the problem is on #1. Last night we ran a compression test, and got some surprising results. 1-132, 3-122, 5-132, 2-145, 4-142, 6-140. So, the whole passenger side is a bit weak. Forgot to drop oil in 3 to see if it picked up the pressure. Yes, its technically out of spec, but he's running stock boost, and its not our current problem cylinder. Told him he could run like that till it finishes dying. I wasn't present the other day (had to leave early), and thought they had gotten spark, but apparently I was wrong. So after the compression test, took the CP on #1 and a known good spark plug, no spark. Connected that same CP to #2, got spark. Back to #1, no spark. Again tested the POS, NEG and PTU connection on CP#1 connector, and they all tested out. There is continuity from the connector on the PTU to #1. Also as a reminder, we did swap PTU's the other day, and it didn't change it. I'm thinking we'll have to look closer at the circuit before the PTU and see if we can find some problems there. There could also technically be a non-obvious short somewhere in the wires for CP #1. Other than that, I'm still burned for ideas. One other note a friend pointed out, we haven't been getting backfiring, so there's not extra fuel floating around (i think).
