new challenger scat pack upgrade questions

So I'm about to order a new 2020 Challenger scat pack 392 widebody with a MT. I want to have some upgrades done and get some hp gain as well as make it sound nasty! After all the research I've done, I'm thinking of the following:

HHP Comp cam 274 complete package
JBA LT headers
JBA high flow midpipes with cats
Barton shifter
Flowmaster original 40's
Tuner - don't know brand yet
running light intake tube mod
resonater delete

I plan to keep this puppy forever and maintain it as best as I can. Any pros/cons to this setup and should I wait awhile to mod so it breaks in properly? I also hear the 19-20's are very hard to unlock the PCM for a tuner. Also, anything else I may need to make this setup run better? I'm going to have the midpipes with cats so it doesn't stink up everything with the fumes as well as attempt to have it pass inspection in TX.
