It will try to choke it as this particular turbo is a long time enemy of your engine.
In all reality what he's saying is that turbo it rather small. It will produce peak efficiency at a low to mid range the the powerband and it will not let the engine flow enough at high rpm.

Agreed that turbo is a bit small for your goal. Are you trying to achieve 600rwhp through a manual or auto car....makes a difference.
Many ways to skin this cat especially since many stock longblock 5.3s are getting to those numbers and beyond. I would say for a budget build: Cam, Springs, studs or headbolts, headgasket, 80 lbs injectors....etc.
One example, Denmah did a setup with a 5.3. VS Racing 7875, ls1 intake, LJMS cam, stock pcm, and 80E...results 540whp unlocked @ 17 psi with 12 deg timing.
