I drove it for the first time last weekend to my brothers house a few blocks away and it stayed at that temperature. I did not want to drive it too far in case something went wrong lol. I asked because it is running rich at idle (10.2 ) I thought maybe its running too cool with the Nismo thermostat and maybe had to put in an OEM thermostat. I am guessing the current base tune needs to be adjusted and leaned out a bit at idle.
