Should i make my efan power on sooner so that my max temp will be closer to 190-200 maybe? I have several temp settings on my DC Controls temp controller i can choose.. i think i set it at 194 which apparently is the thermostat range.

I personally think the coolant temperature should remain in the 200-210 range. The thermostat starts to open at 195, and will be fully open shortly thereafter. The stabilized temperature is controlled by your overall cooling system and the engine load. It SHOULD be above 200 to give you efficient engine operation. With a good pressure seal and 50-50 antifreeze, you won't boil below 250 degrees.
