I do notice that I get the revs up higher much quicker than before, but I can't say the butt dyno notices THAT much of an increase in speed for those revs. Does that make sense? Maybe I'm just nuts or just expected to get a huge difference in raw power. Either way, I'm enjoying the new mod and will be adding the green filter, pullies and possibly a tune.
with the tune and air filter, you will definately feel the increase in power.
