You will have to turn the boost down to make the same power as you are now.
I wouldn't see the purpose in a new fuel system, what you have will handle what you have in mind with a safety margin. I'd guess that more headroom could be had with a -8 line. I wonder if anyone has drilled out the small hole common to the fuel rail connector? It would probably make a difference.
As you know your datalogs will tell you if the fuel system is getting close to being maxed out.
I took a set of stock rails, cut the cross over barb off, and drilled it out as far as as possible. Tig welded male 8an fittings on each rail so 8an crossover line can be used. Also welded an 8an fitting on in place of the main oem fuel connector. Finally I drilled out each injector port to .50". These modified stock rails will flow a lot more. I'm running a return system now so I will let these go cheap if anyone has a use for them.
