As we all know temp is a big factor in any machine situation. I was always taught cooler is better, not cold, just cooler rather than hotter. Regarding operating temp for MY car, I am trying to find the balance point between reasonable power, what my cooling system can provide and what my engine likes or runs best at

Ultimately I do want a pump gas driver, but for now while things are new I want a rocket and the extra $0.10 per gallon for premium won't kill me... In your opinion, what would de-tuning the motor look like? Down the line I may want to reintroduce some sanity

Clue me in please, what is DCR?
