    E38 start up Idle

    what do i need to change to get my truck to stop starting up and bounce to 2000 rpm for a few seconds before it comes back down. I have changed all start up tabs to 625 and nothing is helping. 2013 silverado E38

    Try reducing the start up airflow and maybe start up idle timing.

    They talk about it in this thread.

    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.
