    I def. do see some knock in your tune, Looks like small changes to ve table and Maf table. No changes to Low Spark table,

    i see alot of idle adjustments and alot of high spark changes but thats about it on engine side.

    Kinda looks like you payed money for nothing.

    The VE is basically all stock, they just add fuel everywhere by like 10%. So they didn't even tune that correctly.

    Some timing should be removed from the tune. The high octane table is raised but they left the spark adder table there, so it can add even more timing.

    Power enrichment is still basically stock, it's has long delays that make it take up to 90% throttle to enable.

    You still have stock injectors on a cammed 5.3, good bet it's going to need more injector. Also make sure you are running around 58psi of fuel pressure all the time even under load. And make sure nothing is rubbing on anything that could cause the knock sensors to pick it up.

    I can't view the log to see anything else right now.
    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.
