So you can bolt it on and have the designers tune in place to run it? I don't think that there is any discrepancy in the idea that the track and dyno are not the same. What does hold true is that if both cars are dynoed, never change a thing to either car, and both go to the track, the same results will exist. You are heading towards apples to oranges.

Dyno numbers never tell the whole story. Without a good stock baseline dyno chart of each car, you don't know how much power was gained from the tuning package. I think we've all seen how some stock cars dyno real well compared to others.
