hypertech programer

[working Hummer]

So here's the scoop. The guy I bought it from is refunding me my money back so Yea!. I called Hypertech and told them I have a 30019 and it's not working, that it's giving me that "will not work for this vehicle". They tell me that I must have a old 30019 programmer. I said so! who cares if it's 3yrs or 1 day old the part # is right and it's not working. He tells me that the early 30019 programmers won't work because they didn't have Hummer programming then. I couldn't believe it, why would they use the same part # after they add a new vehicle to a programmer? So apparently the guy said you have to look at the REV # on the back of the unit and it should say 5241450 for the H2, which I don't understand because I've asked about 10 people on Ebay that have them for sale and none of them have had that REV #. So the hell with Hypertech. So be warned if you buy a 30019 programmer it may or may not work for your H2 thanks to their wonderfull part # system they have going there. Sorry if their are Hypertech fanatics here but this whole thing is rediculous, all I want is a Hypertech III programmer that works for my H2, which they say is the 30019 but apparently NOT! I have to also know how old it is and correctly match a series of #'s off of it also. Just rediculous.
