Somehow missed responding to this. Quite sorry.

Is the temp gauge pegged in the red when the system overheats, or is the temp gauge at normal location?

My gut says thermostat stuck closed. The ECTS is in the head and if the thermostat is stuck closed there is no circulation of coolant in the cooling channels. So the ects will read much lower than the actual temperature of the coolant that is in the front of the car down by the thermostat.

What happened as the pressure went up or were you unable to generate any more pressure than that?

MUAHAHAHAHA
This issue has finally been RESOLVED!!

i put on the new reservoir, did the pressure test, the cap was sealed but there was coolant leaking out of the bottom hose on the reservoir. It had one of those goofy squeeze hose clamps, I replaced it with the screw type, repeated the pressure test, and now my system is holding 15psi steady, and there’s no leaking out of the cap or hose.

I have a new thermostat, so if I continue to have issues I’ll try the thermostat, then finally the coolant temp sensor if that doesn’t work.

Well then. Wouldn't have gotten to that anytime soon. Glad it's fixed. Forget thermostat suggestion---you'd be overheating.
Nice clamp, dude.
