Honestly, efi and a stock turbo, stock injectors, and stock cp3 will get you to 500 hp. Take 06s advice. He has done this many times. Get a goal. You need to read on here till your sick of reading for a month, then read that much again. It's not worth trying to rush it and jump in on everyone's recommendations. Only you know what you want to spend and if your going with 30% over injectors and a stroker pump from Shane you will have the fuel for solid 600hp, as long as you replace your lift pump too.
Do yourself a favor and read about others setups and get an idea of exactly how much hp each part can support, then how much you want to spend and go from there. Your stock lift pump will only be good for about 500hp and if you don't replace it you should even waste the time upgrading the rest of your list cause stock sized parts will get you where you want to go.
Not trying to sound like a (butt) just my honest advice to keep you from spending more than you need. I've read tons and when I started I knew next to nothing. I now have a very good idea of what I want my truck to do, and the parts it will take to get it there, even tho I'm not entirely decided yet.
