Do you have any other people with your radiator that it cools too well? For example, if it's under 60 degrees outside, and I put the car on the highway, in a matter of 5-10 miles my temperature gauge has fallen back down to 100 (the lowest number) {Fan doesn't turn on until 170, off again at 160}.
On the flip side, when it's 80+ (don't know the max yet), I can turn on my 2nd spal fan and watch it drop to 160 (which is great!) in about 10 minutes, sitting still (moving it's much quicker)
 
Thermostat stuck open? If it were working properly, wouldn't it be keeping the water temp in the block at 160?
 
I have one of Nick's cores and an upgraded waterpump and have not seen that problem. Does sound like a thermostat, but if by gauge you mean an actual addon, I'd suggest checking the ecm value with a scan tool.

HTH,
Tom
