Default Dash temp gauge

Thermostat is good. Engine heats up. Changed coolant temp sensor. Why does my dash temp get to about 135°? Please help.

I have the '99 V10, with a 190 thermostat. The gauge reads low also. For more accuracy you could hook up a mechanical gauge.

Plug a scanner into it, and see what the PCM thinks engine temp is.
