Did you check the actual temp on the console? Curious what it's actually reaching. I've had mine creep up to a bit over 200 on hot days, with the A/C blasting, while stuck in traffic.
You could have an air bubble in the system.
180 should be 180 the computer can't change it

Sounds completely normal. I wouldn't worry about it. Just check the level of coolant after a few decent length trips and top it off if needed.After a 30 min drive the highest temp I saw was 188 momentarily after acceleration with the majority of readings being 183 or 185. I can say that I was definitely seeing mid 190's or higher earlier today in 75 degree weather based on gauge position. Possible explanations are a finicky thermostat, air in the system, or a computer compensating for lower temps in some cases. Most likely it is air in the system, followed by a finicky thermostat as a runner up possibility. I did have the truck idling with the cap off the radiator for like 10 mins though.
Whats the gain to go to a 180* stat?
The thermostat controls the temperature not the computer. The computer adjust everything by the temperature

The tstat controls the temperature of the coolant leaving the engine.
The fans control the temperature of the coolant leaving the bottom of the radiator.
Changing one ( tstat) without changing the other ( fan settings) will result in erratic unpredictable temperatures.
Most likely result is the tstat wide open with an increasing coolant temp until factory fan setting is reached. at that point all of the coolant will be at the same or near same temp and it will take some time for a differential to be created between the radiator and the engine and the lower (cut out) set point to be reached for the fans to cut out.
this can lead to a false belief that the tstat is bad, or the "computer has adjusted itself." IN reality, the observation of temp is more controlled by similar daily drives, and deviating form that will lead to new temps that can be confusing
Tune your truck, set your fans for the tstat and no worries
with a 180 tstat and proper fan settings normal temp is usually 185, and will go up with load, WOT runs towing etc, but will always return to 185 once the condition is removed.
