    Stock GMC Jimmy Tune file?

    Is there anywhere to find a stock tune file for a vehicle?

    Oddly enough I'm trying to get my conversion past the referee in california and he is requiring it be california compliant and not a federal vehicle. Besides adding another cat I need to swap the computer calibration from federal to california. Does anyone have the stock tune file for a 1999 GMC Jimmy or Chevy blazer with a 4.3 that is california emmissions and no air injection?

    I'm guessing I'm going to have to buy another computer, another set of credits to make this work.

    Thanks,
    Kevin

    Thanks man!

    Do you know that those are Cali emmisions and not federal? I found the file repository here on the hptuners website, but without running each vin at the dealer and getting the RPO codes there is no way to tell if its cali or federal.
