Just to clarify, some EFI systems operate at 43.5psi, the later LSx engines operate at 58 psi. With aftermarket systems it does not matter. You just have to choose your injectors based on the pressure that you will be running. Make sure you are aware at what pressure the injectors are rated. Also be aware of the fuel pump output at various pressures that you plan to run.
