ooo, for the the kansas city area unless you are gonna burn a chip or use a stand alone, you mite be SOL. here in KC there are roughly 5 dyno's, 4 of them are within 5 miles of each other. if you are going just to get some numbers/baseline then any of them should do fine. if you are gonna do a chip, then i would reccomend supertune. i think they still do custom chips.
