After all that is when I noticed the poor flow when hot with the cap off.

I might be having both problems, too. Cold case claims their 12” fans provide better cooling, but once I get this guage figured out I’m going to swap the fan clutch and shroud back in to compare. Maybe I hurt myself with their smaller option electric fans.
My fans kick on at 190, thermostat is just a 180 thermostat from autozone. Would a lower temp thermostat help me?
My brother advised that I get one of those funnel things to really make sure the rad is burped correctly, and troubleshoot the waterpump. He agrees that it sounds more like a heat than a tuning issue.
