You may want to look into getting a walbro 255lph Hi pressure fuel pump. The FMU is kinda like a fuel pressure regulator, if it's a 12:1 ratio FMU it will raise the fuel pressure 12psi for every 1 lb. of boost it sees thru the vaccum line. Example say you're running stock fuel pressure around 35psi and boosting 6 pounds, your fuel pressure will be around 72psi. They also have 10:1 ratio FMU's and ones with smaller ratios, type in vortech FMU in a search engine and they should come up. In my opinion I would get an FMU, injectors, fuel pump and have someone tune it.
