    Lightbulb Has Anyone Touched the 3.9L LZ9?

    I have a 2006 Pontiac G6 GTP (now had an impala with the same motor before). Im looking for help mainly just push the timing for 91 octane but anything to help add a bit of power and clean up the shifts would be appreciated. I'm more computer savvy than car savvy,
    thank you

    Post the tune. I don't know what it looks like at the moment. I'm sure there might be some easy stuff to adjust being that it's a GM car.
    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.
