2008 RCSB 4.8 turbo

I've decided to go with a trick turbo kit with a 72 mm turbo and what I haven't figured out is what gear , stall , spark plugs and injectors to go with . I have a built 4l60e that I know I'll have to upgrade in the future but as of know I'll take it easy on it . From what I've read I have a fuel pump control module that controls my pump so I should be ok to 450whp . What spark plugs and gap do you recommend? The truck currently has a 3.23 gear with an open diff , so I ordered a true trac and can't decide on a gear . Which would be better 3.73 or 4.10 For a 4.8 ? And I have no clue on the stall 3200.. 3400 ? 60lbs injectors good enough ? I'd like to get y'all's feed back and see what others are doing to y'all's trucks ...

Mostly hwy driving then the 3.73
In town short runs 4.10. Also what tire height and your own driving style plays into this.
I drive with 4.10 and a 3 speed 400 for years. hwy 3000+ rpms not running with traffic gets old.
60lb injectors are fine for most builds.
