CK - 120-130 bar
ME - 130-138 bar
MF - 155-163 bar
I find they run MUCH smoother if you get all four injectors within 1 bar of each other.
My engine is 1V, same pop as MF
Checked the IP internal fuel pressure. Still ok at 45 psi at idle.

I got the dial indicator out and my timing was at 1.36 mm!
I sanded the injection line more with 400 grit paper and tried the timing piezo again and was able to get steady RPM and strobe readings. I retarded the timing to just a hair more than 12 deg BTDC and at this setting, the dial indicator says it's at 1.06 mm.

I am borrowing Orcoaster's nice chart below, which indicates he is getting very different results with his diesel pulse adapter. For me, at 12 deg BTDC, my dial indicator says 1.06 mm timing. Orcoaster's chart says at 1.05 mm, it's near 21 deg BTDC! Why is there such a big discrepancy?
I think most likely his injector(s) is(are) crap and starts peeing a stream when it shouldn't, which the pulse adapter reads as the pulse. I've said that his results were very much at odds w/ my experience on a whole lot of injection pumps and that something wasn't right with his readings.
Your results very well match mine. Stock 155 bar injectors in decent tune with a stock pump in good tune - 12°=1.05.
Still haven't emptied enough bottles to get the rebuilds done. I sent the pulse adapter back but I could swap and injector on the one I tested to see if it drastically changes the timing. Might do that once the exhaust gets welded up. For now the engine needs to be quiet and not disturb the neighbors.
