In a private discussion with PRH some time ago, Dwayne said dynoing was much better than trying to tune at the track, despite my car being consistant. He was right . Since that conversation long ago, i have dynoed five combinations, and EVERYTIME have found power i would not have otherwise found. On top of that, problems were found during the dyno sessions that may have cost me a weekend of racing, which equals the cost of a dyno session for me . I hope this reachs the engine owner.

This is true and valid. The dyno is a tool but, there are a few that can do well without the dyno. Having data acq on a car helps too! I know of many who dyno and then don't check anything and make adjustments BECAUSE they went on dyno and then their junk doesn't run the way it should. If a car isn't easy to work on (remove/install engine) then that's another reason to use a dyno.
