I have never seen any additional power by running the engine cold, it also increases the timing needed for a complete burn, and increases emissons, and reduces fuel economy.
Let's not think we know more than GM Engineers.
My Recommendation is Leave the T-Stat Alone.
Everytime I dyno one of these cars they make the most power when FULLY Warmed up.
Usually the 3 runs or more before it stops gaining power, What does that tell you?
