I understand you point, but the dyno does not lie. It may not give track performance, but it is the only accurate way of determining exactly what power and torque you are putting down on the street. So what is the best way to measure a car's performance? On the track? What about the human error, track conditions, tire selection, etc? If you read my post, I was referring to the difference between 3 graphs with different opening points. I think it's safe to say that the dyno is gospel for that type of comparative analysis.
