    Does the computer support DBC, as in it has the IAC drivers on the circuit board?

    I believe you have to change the systems options from 1 to 0 for the ETC as well.
    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.
