VF VF570 Kit and 5xxwhp

Hey Guys,

I have been working on a E46 M3 and looking to produce 5xx whp. The car is currently running the VF Engineering VF570 with the following mods:

Full Catless Exhaust
2.7" SC pulley
Rogue Racing Accessories Pulleys
I believe the VF Kit runs 440/550cc Injectors
4.10 gears

Mods that will be installed in the next couple days
AEM Meth Injection Kit
Upgraded Fuel Pump
Upgrade Fuel Injectors (looking at 775cc injectors)
Install 6" Crank Pulley
Fuel Pump Regulator
Custom Tune

So here are my questions for the boost gurus:

1. I have read that the stock fuel system can support up to 500whp, If I upgrade my fuel injectors, fuel pump, should I upgrade the lines as well?
2. What injectors should I look into to? I am looking to make about 550whp if possible (I know I will be building a motor in the winter)
3. What other modifications should I look into doing?

Thanks for the help!
