If you keep jetting up and it goes faster, and you go more than 4 steps up in the front(or rear), .. and you street drive the car you can trade some of that fuel over to the power valve channel restrictions(PVCR), enlarge them and go back to leaner main jetting for economy. Get the best of both worlds that way.
Sweet, thanks! I guess I should try going up some, and down some and see how it responds.

Yea I've heard about drilling out the PCVRs. That's one thing I eventually want to try when I get the WOT tune down. I'm kinda nervous since it's irreversible, but metering blocks are cheap anyways.
