    What is different on the 2002 Chevys that this particular hypetech is ONLY for 2002 models, I have a 99 but found a hypertech for $50. All I want to be able to do is change the tire size, so will this really not work on a 99??

    the pcm's could be different, in which case no, since it's made for a 2002 only, it will not work on your '99...
