    2004 chev suburban throttle tuning

    I have a 2004 5.3 from a suburban that I swapped into a 81 k5 blazer when you push the throttle to wot from a standing start it feels like a older car with a carb when they bog, I feel that it is some kind of lag between when the pedal gets pushed to the floor and the ecm sends a signal to open the throttle body what tables should I be looking at to tune this out?

    Post the tune and logs.
    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.

    Sounds like it may be the OS that has an factory update for a "throttle progression" issue. The new updated software fixes the problem and doing a compare from before and after you can see the areas that are changed regarding the throttle. Pull the tune and check for updates.
