    Good tune for what though?

    Stock vehicle or what is the setup?

    All I can really see is that it's a G6 with a 2.4 engine. It must take you forever to repeatedly try to take this thing to 127mph, not sure why you'd need to go that fast in a G6 lol. The longer you are in the throttle the lower the o2 sensor voltage gets, so it's slowly going leaner over time. But without a wideband it's hard to say what it's really doing there.
    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.
