    A few things.

    1) watch the video: https://www.thevicshop.com/forums/discussion/video-2005-2007-100-performance-options/

    and then realize that the 501 cam in that bike isn’t what I would have chosen because it’ll kill the low-end performance (in favor of a high top end).

    And realize that the Lloydz re-program would have been a way to salvage some low-end by adjusting the ignition timing. You’ll have to re-dyno the bike if you decide to do this mod.

    2) You’ve removed the baffles from the bikes which will reduce the torque output at lower rpms.

    3) I only deal in miles per gallon, not miles to tank. If mileage is a huge concern for you then you’ll need to be scientific about your MPG data collection so you can compare to the data from “after” the Power Commander is adjusted to improve mileage.

    Basically, you’ve picked a high-revving set of mods – a big cam, wide open exhaust, then geared down the final drive with an underdrive pulley. It is no surprise the low-end torque took a hit in power and that the bike gets poor mileage because it has to be revved so much to wring the power out of it. It is what it is. Or now you know, and can make changes accordingly.
