scangauge coolant temp accuracy?

Well, I just installed the new 192 degree thermostat in my Paseo, the stock one is 180. Previous to this the coolant temps hovered around the high 190s, low 200s. So, I got the system all worked out and went for a drive. The coolant temps quickly spiked up over 200 and seemed to hover around 211 (about 12 degrees warmer ironically). So, my current thinking is that the coolant temperature readout from the scangauge is not correct. I further tested this by idling (and some revving) the car in my driveway to get it up to the temp that the fan kicks in at. According to the manual this temperature is supposed to be 201 degrees. Idling the car today it didn't kick in until 216 according to the scangauge. So, I'm thinking the scangauge is off, or my coolant temp sensor is going crazy. Ideas?
