This isn't a bad idea. More data would be useful. One hot cylinder gets mixed with the rest at the collector.I've been meaning to drill my manifold for 4 pyro probes, so I can watch the power balance with the junk nozzles I've been running
Maybe you should do something similar, then you'd see one was running real hot long before you'd run it hard enough to burn a piston.
I've been running into this lately, low egts with black smoke. Confusing because usually smoke means too much fuel, and therefore high EGT...EGT's are low! On a long pull, it barely cracks 600°C. Little smokey if I am hard on the accelerator below 2,000 rpm but once the turbo lights up, down to a light haze.
I'm not surprised by smoke down low with such a big turbo. Will take some fine tuning to clean up the smoke on the bottom rpm range without creating more lag, but I think it can be done.I've been running into this lately, low egts with black smoke.

I think that I'm just running too much injection timing advance, but haven't bothered to fiddle with the maps :\
