Foxwell data for ~80 mile round trip.
Pic#1 - Cold start and idle for a few minutes. Temp 115F
Pic#2 - Temp @173 running 70 MPH
Pic#3 - Temp @180 running 70 MPH
Pic#4 - Temp @183 running 70 MPH
Pic#5 - Temp @183 MAF 0.04 lbs/s

I'm actually surprised. The new thermostat runs cooler than I thought. It was a cool morning. Plus the mechanical fan clutch is new. 193F was the highest temp I saw. Adding and subtracting STFT and LTFT = ~0! STFT did go up and down on hills vs straight road.
