Most hp on return less system

Nissan370

Being that my goal is 600rwhp
And the fact I am tring to not get parts I may not need

How much hp can be had on the returnless style system

My setup
340lph fp and 750 cc injector
Snow performance water - meth system
6266 single turbo

Water meth will be install in next 3 weeks
and I have a set of 900 cc injectors not installed yet

Was going to do return style but I wont do it if I can reach my goal without it
