I have a 2000 Taurus SE sedan with the 24v Duratec engine. Other owners of the same car that I know can peel out their front tires easily by flooring it and mine will not. Also, i 0-60'd in 9.27s and, while it was a cold day, this seems awfully slow. I believe it is running lean also. What can I do to increase its performance to where it should be? How much would a PCM tuning help?
