Sorry for late reply. Holidays really messed up time. I would only lower the thermostat temp if I was in a normal condition with engine temp. and went to programmer that would in turn allow Me to run cooler thermo by telling computer you were doing so. Of course at same time getting the benefits of other options of programmer.

The only other way I would run cooler T-stat with stock tune is if You are in a hot temp part of the world and needed the cooler T-stat to try and get to a cooler engine temp and maintain a stock engine temp.
