Default Overheating over 75mph

Hello everyone,

Having a small issue was the new WS6. I can drive an hours, with no issues under 65mph, temp at 210. Once I get over 70, she starts to heat up, especially at 80mph, she jumps to 230+. I can turn the heater on and she drops back to 210. There are are leaks that I can find, Radiator is topped of, and had a flush 3 months ago.
I am in Central Florida and it been getting warm this week. Last week when it was cooler, I did not have this issue. Coincident, probably, but stating details.

Water Pump or something else? To my knowledge, Water Pump is Original.

Tstat not opening or an air bubble in the system.

Tstat should be opening around 175-180. If I am running an hour at speeds under 60hmp for an hour, should that Tstat, not be opening. Would it not start over heating earlier?

Already, did some more afternoon driving, and really ran Torque the whole time. Saw temps get up to 260, then finally appears the Tstat opened, and things cooled down. New Tstat tomorrow morning.

Good Call, thanks.
