Dyno data isn't meaningless unless the variance is just a few hp (~5hp plus or minus). When I see a dyno of a car with test pipes and tune with ~40whp more, that has meaning. But I've dynoed a car back to back with the same car putting down a few more or less hp 5 min later (hint: it wasn't because the car got more powerful by sitting still 5 minutes). I think pitting 2 main tunes against each other in these circumstances is kind of silly, since the hp variation between the 2 is almost certainly less than 10 hp (2-3%).
What I'm getting at is that even if the cars were 100% identical in terms of wheels/tires/options and same driver, the results would not mean much. Add those variables in, and it is worthless (except for fun).
Having a run like that for fun is fine of course, except that a lot of people are going to watch it and say "oh gee, tune #1 won the race so it makes more power!"
