Is there any performance benefit to using a 180 degree or 160 degree thermostat instead of the factory one which I think is a 195 degree? I know these would make the engine run cooler but would they make it run too cold and not run in closed loop mode as the car should? Currently my temp gauge sits at 190 when cruising but can climb to 220-225 when I run it hard. Any info would be helpful.
Thanks in advance
Adam
