    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.

    What's up with the MAF sensor curve? It appears to be reversed. It goes from high to low flow.

    Yes, it works like that, on my case, it idles at around 3000hrtz and goes to 940-950htz at WOT with 80KPA of boost.
    Also fueling follows MAF table modifications nicely..
