    I don't think you need that yet. Start with the VX rpm kit first. Purchase from the online store here and get 10% off.

    Welcome to the forum. I don't think an EFI controller is necessary or helpful on the VX's naturally aspirated motor unless maybe you raise the compression. Try searching for posts from Italianstallion314. I think he's done some mods with a VX.

    A fuel tuner is needed to re-adjust the optimum air fuel ratio AFTER you make engine mods that affect it. Used by itself=waste of money.

    Could you be more specific as to when the fuel tuner would be helpful?

    if you raise compression by shaving your head or pistons, add turbo or supercharger, pretty much adding large amout of air to your motor will you then need the r and d fuel tuner.

    Do you think adding the tuner with the Riva air intake would make a difference? Or does the intake make any difference with air volume?

    Thanks for your patience!
