I just bought a 2005 Z Enthusiast model and have been hearing conflicting reports as to breaking in the engine of my new car. Personally, I wanted to wait after 3,750 miles before I "opened" up the throttle of my car and started using it for all the horsepower it has. But, I am being told by some people at work that I should go ahead and open up the throttle right now to break in my car. What should I do?
