At the end of the day the dyno is really just a tool, there are too many ways play with numbers. This is why we took a baseline each time that way you just focus on the gain not the end numbers.
Anthony - Agreed 1000% - that's why I would prefer to see the pulls all on the same dyno. better yet to have done them on the same day so the weather conditions would be similar, I realize that is more difficult. If the same dyno was used then the difference in the numbers would be more relevant IMHO. the different brands DJ vs Dyno dynamics (iirc) makes it harder to compare in my view. of course the proof would be at the track.
