I'm preparing to boost my 5.7 very soon, and I'm trying to put a list together for a fuel setup since I'm getting a tuner kit. Ik a lot of the blowers come with a boost a pump and bigger injectors. I'm thinking of getting hellcat injectors, a 392 fuel pump (my stock pumps got 70k miles so I just wanna replace it) and a boost a pump. I'm assuming this should be good enough for just 7psi, but if I decide to turn it up down the road a little bit what's the limits on a setup like this.

You asked in my thread and I didn’t fully answer. I currently have Hellcat injectors as well. But I’m planning on upgrading once I decide to turn up boost. The 392 fuel pump is very stout. It should support 7-8 psi no problem. I have a billet drop in adapter for the factory hat that can support 2 pumps. Right now I’m running 1 450. But may add a second one down the line. I’m replacing factory lines with AN style setup and boost reference regulator. For your application your idea is perfectly fine. I want a little more boost so I’m over building my setup.
