I’m actually working in this same thing.
I would say good advise can be viewed on DRD youtube video about the emissions intact tuning.
When you take away one thing just know that you have the potential to put more stress on the SCR and or use more DEF.
You still could benefit from trans tuning and a mild tow tune though which is what I’m testing on my truck, then moving to deletes.
Ill be posting more videos on my channel as I progress. I did have my 14’ deleted and ran it emissions intact for about 30k.
Runs way better without all that mess.
