    1997 4.3 sonoma

    I have a 1997 gmc sonoma with a 4.3 and manual trans. In the vehicle list i see a 1998 4.3 sonoma listed. Will the software be able to tune my 1997 sonoma?

    No, because the 97 computer isn't supported.

    If you somehow made the 98 computer/harness function in your 1997 body, then you could tune that.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
