With my supercharger I have a 160* thermostat which makes the engine run at about 175*-180*. I have heard that when the PCM is not tuned for the lower temperature, the engine may run too rich thinking it's still in warm-up enrichment mode giving good throttle response but less milage.

GM has designed these motors to run at ~195º for a reason......within reason engines function better the warmer they are (this is a proven scientific fact!!), The ONLY reason there ever was to go to a lower temp thermostat was when cast-iron heads were popular, cast-iron is a heat-sink and warms up VERY fast, to cool the chambers enough to prevent detonation on hi-po motors 160º thermostats became popular...now that aluminum is used almost exclusively for cylinder heads the 160º thermostat has become a pointless modification.....
