Whitedog said "Why would you go with a FiTech system, when the OE Fuel injection is already tuned/made for the motor?"
FiTech is a totally standalone unit. You install a wideband CO2 sensor, supply and return fuel line and that's about it beyond the throttle body injection unit and a simple wiring harness. No adapting the factory wiring harness or computer. The FiTech unit is self-contained with a internal computer to run the show. It looks pretty much like a carburetor and is tunable with a remote unit in the vehicle. You do install a 50ish psi fuel pump. The internal cpu can control fans and even ignition (depending on what you're running).
I could have gone with factory fuel injection on the vehicle I'm running a FiTech on, but wanted more of a old school (read 60's very early 70's underhood look) clean engine compartment uncluttered by wires and hoses. FiTech filled that slot. Clean looks with all the advantages of EFI.
