Stock, I believe, is 195'F thermostat.
Depending on where you mounted your gauge too... I mount mine on the driver's side front of engine. I get consistent temps there. I have a 180'F (wouldnt recommend lower as it screws up your computer into rich...). At idle its a little warm (underdrive pulleys), but on the street its rock solid 182'F. At the track I never go over 205'F with the big Griffin radiator.
