    2003 4.8 tune on a 2004?

    I'm looking to put a stock tune back on a 2004 chevy silverado 4.8 2wd auto. There is nothing in the repository for an 04, but there is an 03. Can I load up this tune without issue?

    Do a search in the repository for 2004 and 4.8, no other search terms. There is one in there for a 2004 Sierra. Open that, open a compare file, change all the changed tables in your modded tune to the ones from the stock tune. Shouldn't be a problem.
