Why a 195 t-stat? I see a lot of recommendations for a 180, and that's why I bought a 180. I'm not putting it in until this weekend, but if there's an excellent reason for sticking with the 195, then I'd like to hear it.

I see some people say the gas mileage is worse with a 180, but I know my GTP runs A LOT better when the engine is cooler.
