But what you do get is a system which will begin to cool your engine at an earlier time. It is very helpful if you have mods whihc increase output dramatically....they can make the engine run much hotter, and you do not want it to run any hotter than it does from the factory!!

You could try a 180 thermostat

All of the above statements are true. More power, less gas mileage, more engine wear, worse emissions, need to reprogram the fans.
If you don't reprogram the fans you cooling system will circulate sooner. You may get a cooler version of heat quicker, but it will take longer to get to 200º F. No real harm done there.
I put a 160º thermostat in one of my car before it was a TPI 350 V-8 in a Formula 350. I didn't get much from it. I think it shifted a little harder. So you may get harder shifts, but this temp might not be good for the tranny I don't know. Too hot is no good and too cool is no good also for both the engine and tranny.
Todays engines are designed to run at higher temps. But putting that aside. Cooler air going into the cylinders because of a cooler engine will results in a denser fuel and air mixture thus more molecules of air and fuel will enter the conbustion chamber and the result will be more power. This is what a turbo or supercharger does, but they force much more air and fuel into the motor at any temp.. A cooler motor results in the same thing but on a much smaller scale and with no force. It's just one factor in the whole computation on any motor.
If you were to have a heat problem then you might change the thermostat and fan programing for that reason. Years ago the cars used to run 180ºF thermostats. So I'd say , in my opinion, that's a safe temp to run your car with the fans reprogramed. However, changing your thermostat temp might void your warantee or cause you to fail an inspection (not sure).
