Thank you all for your input. I would have to agree with Zef_66 that I do not see it as being essential if you properly mod it. My car only has CAI on it for now. I do plan on doing additionally stuff but does it make since to have a cooler stat with the onset of winter in chicago. The car does need some warmth to keep things moving correctly. Logically there is no point to do it until additional mods are made and level are monitored in both city and highway driving.
