Nice write up. It's great to get some v6rs in on the modding action. Your engine will not self implode and you are far from the danger zone so no fear of cataclysmic over cooling. No need to cover the polar ice caps with carbon soot. Again installing a lower temp thermostat will not increase horsepower it only increases the probability of the PCM choosing a more powerful fuel and timing map under heavier engine loads. Tuning your fans to come on a little sooner will keep you out of heat soak if you feel like modding further.
