I don't think a dyno is really gonna show much over 1 HP, but I believe they compliment existing systems and add a positive to the power curve, no matter how small. Its just one of those things where you gotta want to make the small improvements, to compliment your big ones. I don't neccessarily feel horses as much as its just a little quicker on the rev past the 2500 mark, and a little smoother.

To be honest, for me, it was more of a thing purchased with spray in mind.. as well as the bigger throttle body, that I may dyno with/without spray, I think the science is right for that set up, as well as F/I, but in any case an improvement none the less.
