This pic shows as low as it would get stabilized with fairly frequent misting. High side under a heavy stream of water would drop much lower than pictured, below 150, but regardless low side never varied off of around 55psi.

I did check front evaporator outlet temps constantly while adding the cans, mid way through the 4th can it started to plateau and remained +/-2 degrees of the min temp until that can was empty.
@1998_K1500_Sub My actual temperature probe broke somehow so I am stuck using the multimeter probe lol. It's a junky china one I got from the jungle website. I really need to pony up and get a decent Fluke.
Here's a real head scratcher. I measured the temps at the suction inlet of the compressor and it was far colder than the exits at both front and rear evaporators, like 58° at idle. I would expect it instead to be about the same if not slightly warmer...
