My car never goes above N or O on the stock gauge with the 180* thermostat. Check to see that you screwed the coolant temp sensor all the way and that it is functioning properly. After I installed my intake, my coolant temp sensor went bad and my gauge was all over the place. Plus I didn't have it screwed in enough. Hope this helps.
