Just so you know, you will get zero help with this post.
Help us, help you.
We know nothing about you, your vehicle, your problems and your questions.
Details will go a long way in someone being able to help you in anyway.
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.
