I noticed that too. Mine doesn't rev quite as high (maybe 1200 instead of 1500) and it "lopey" like it has a big cam lol! Also, I thought that my ICV was going bad (revs going up and down during cold starts) and that is virtually gone now.

As far as not being able to FEEL a difference in performance, that's not terribly surprising to me. The "butt dyno" is gonna have a hard time detecting a 3-5% change in power. We are talking about 10-20 HP here compared to 400+. That's "in the noise" for the butt dyno IMO.
