Dave, one way to verify the coolant temp compared to the gauge is to use an infared temp sensor on the back of of the thermostat housing. Mine runs about 170f max at long idle on a cool 70 degree day. My guage never gets past 3/4 even when running on a 90 degree day. Usually just to the right of center. You can find inexpensive IR's on ebay. Maybe Grainger or Northern Hydraulics or a Fleet Farm type store will have one locally.  Have you replaced the thermostat and if so with the 2 stage one? Best of luck.
