You can add a fuel pressure regulator to take advantage of the higher output pump. Casper makes an exact fit FPR. Cartech also makes a good FPR. Other FPR's are good too. Check out Summit racing and Jegs. You should also add a fuel pressure gauge for setting the fuel pressure. Injectors are really not needed unless you are doing extensive engine modifications such as turbos, superchargers, etc. An adjustable fuel pressure regulator will give your engine all the fuel it will need. Stock fuel pressure is in the 45-57 psi range. Adjust from there in small increments.
