Maybe someone will be able to help you locally but it's still mostly going to be all custom because not every vehicles requires the same changes. Nor do they repond the same way to mods.
If you have the software already it would be a good idea to learn to use it and understand it. For sure the MAF curve and VVE table will have to be tuned for the change in intake tube size and pulley size.
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.
