Where's your sender mounted? How accurate is the gauge reading you're referencing? Don't be afraid of 200* coolant.

In Texas heat, idling with A/C on my temp gauge can creep up to an indicated 225* F and will fluctuate between indicated 215* - 225* F as the fans cycle.

My gauge gets its reading near the head and my EFI gets its feed from the thermostat housing...the two are roughly 10 to 15 degrees apart...EFI being lower. Whether either sending unit/gauge combination is exactly accurate or not is unknown but I feel confident in the EFI reading being the one that really matters as far as knowing whether it's running at safe temperatures.
