Ok, from some quick napkin scribbling, the refrigerant charge and outdoor side looks to be in the standard operating range. The bottleneck here seems to be the brazed plate heat exchanger and or too much heat sink and or too high water flow rate through the brazed plate heat exchanger.

The devil is in the details. I haven't seen any information about the indoor heating setup, so that part of the story is still a blank. Staring into the void, I would say measure the water flow rate through the brazed hx and calculate your heat flow. Slow the water flow down to see if the parameters change. If you find a happy place, you're golden. If not, the numbers will point you in the right direction.
