Coolant temp fluctuations

I just recently changed the waterpump, fan clutch and the thermostat. The temperature varies quite a bit. At idle or constant speed, the coolant is "normal", but whenever the rpms increase - going up a hill or sitting in the driveway and depressing the acceleartor, the temperature drops to the just above the cold mark. I'm lost as to what i should check next. My truck is a 1992 f250 4WD, 351W.

Any ideas??
