Dynos and tracks tell DIFFERENT stories... Dyno will tell if power was added, and if so where and how much... Thats all a dyno tells... The track wont tell you how much power was added, but can tell you where (top end or bottem end) and whether or not it was... A dyno ONLY talks about power numbers and whether they go up or down, a track tells the whole story, if the mods were worth it, if the car ran better or worse, if for some reason because of the mod you have to revamp your driving style (in cases of big power adders mostly)! I know what your looking for 5-speed, you want us to say, yes the dyno shows if a mod adds power, better than a track does, and yes this is true, as a track doesnt flat out tell you a mod added power... But if you want people to agree its going to be tough, even though I see what your trying to say, its going to be read as a track vs dyno comparison, and I doubt you will get manu people supporting a dyno over the track! A dyno is one way to tune a car, other than that it really means nothing, as there are tons of variables to how a car performs, other than horsepower (and thats where the track comes into play)!
