The most likely cause would be either a seized thermostat in a "fail-open" mode, or a missing thermostat all-together. Are you getting any heat from your vents? If not... then you probably need a new thermostat.

A stuck thermostat would yield a low temp... for a while. But eventually the temp would come up to full. My old set up (previous owner + build) had the haltech temp sensor drilled and tapped haphazardly blocking the t'stat. My car would take about 20 minutes of driving before seeing the water temp gauge reading normal. How long is the car running when you are taking the reading? If it's after than an hour, then we can definitely say it's the sensor.

it wasn't long i drove it around for about a hour the other day and the temp went up to 130 ish i tested the sensor in a pot of boiling water but when i took the pot off the stove and walked out side it cooled down and my sensor read only 193 so i'm sure it is working right i just don think the sensor is far enough into the coolant i checked and about 1mm of the sensor was only in the flow.

Are you sure where you drilled the hole for the sensor, that the sensor is now reading the output of the radiator going into the water pump instead of reading the output of the water pump going to the radiator?
Once upon a time..........I installed a sensor in the passage where the drain plug for the *block* is. It read low temperatures/false readings. Because that passage is a dead end passage and ther is no water flow in that particular passage. Just FYI. Not much to do with what your doing.
