Hummer Computer
I bought my 04 H2 about a year ago and it has at some point had a programmer put on it. Does anyone have have any suggestions on how to get my computer programmed back to it stock settings without the original programmer. I have taken it my local dealership and have had the computer flashed back to stock already. I bought a new programmer but when I hook it up it says that the computer in not stock. Any suggestions?
