    How can we help if you don't provide the tune file to look at?

    And you didn't list all the parts you used for the AFM delete.
    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.

    If it has a CEL for the DOD then it will turn off the spark/fuel to that cylinder. Make sure the codes are disabled. Also you will need to add idle airflow for the new cam otherwise it will probably be prone to stalling.
