yeah, thats kinda what im figuring. if i ever get on a dyno i might set up a second tank to do a comparison just to see but it's not really important. i've seen and heard so many people talk about how they run this and its a big power increase, or pour that into there tank and it runs sooooo much better... i guess if i get around to it, i'll find out one day lol. it would be nice to see on paper what if any difference stuff does, like that fuel additive chart somebody came up with for lubrication on here.
