Can we get some specifics on what thermostat and coolant line was changed?

I popped all the grille shutters out (left the motor plugged in and the one shutter attached to it intact, too keepthe computer happy). I now run at 195-199℉, unless I'm idling in traffic. I also noticed a .5mpg improvement in mileage!
