twins for built motor for the street?

I have searched alot and I am just not knowledgeable enough to decide what setup to run for twins on the street. I have a 03 qcsb and still want to drive it on the street and possibly tow 6k once a year(camper)



Mods

Carrillos, mahle .040 pistons with balance bottom end. All arp studs/bolts hold it together also

Motorsports diesel side draft with 6.7 rail and lines

Twin ats cp3s. Both stock

Flux 7.5s

Extreme duty push rods and 110# valve springs

Port n polished head

Stainless diesel t4 manifold

625 arp kit

188/220 cam( maybe different dunno yet)

Gonna have a bigger intercooler just not sure what yet

Smarty touch/udc. Tuning will be determined later on but more then likely firepunk

Airdog 200

Built trans with billet shafts through it ( stock stall as of now)

And I'm sure there's more just can't think of it



So I'm thinking a s464/71/.90 over a s482 with a 1.1 housing and external gate for the setup.

I'm just worried about my injectors, but was told they can be tuned for street with a twin setup and not be Smokey.



I also thought of a s466 for top charger also.





I have searched and there is alot to read but I want honest opinions on this setup. I will do some drag races and pulls for fun.
