    this is my first post on this forum.
    I'm considering buying an Uplander and want to know if there is anybody out there who knows if there are any mods (cold-air intakes, headders, exhaust systems, chips, etc.) available for the 3900 motor. I'm particularly interested in increasing the mpg (a bit more hp would be nice, as well)
