Well to go out and buy them outright to swap from VF2's with no actual numbers/dyno results, im gonna say probably not. VF3's, yes. I work in engineering/technical service, If I told guys to change parts because "they felt more powerful/crisper" I wouldnt have a job anymore lol. People want numbers, period. Everyones opinion on power mods are different. One guy might think the gain was huge while the other guy doesnt, thats where numbers come in, facts. Like I said in the beginning, i know they make a difference but I wanted to know how much and if anyone Dyno'd them both. isnt that the point of this whole thread? Thats all im saying. Like Tyler said, we havent seen any Dyno sheets yet, thats whats most important to me.......
