well for a proper operation you will also need an o2 sensor to keep your computer giving a proper fuel mixture.... as well as a manifold absolute pressure sensor(map) to let the computer know the load condition on the engine.... depending on how much you're boosting you'll need different injectors as well as a high pressure fuel rail.... i know the stock escort ones only have about 9lbs.... but since you're boosting you'll want more like 15-20lbs rail pressure with your TBI..... also you'll want to make sure that the TPS on the throttle body works properly to give the computer a better knowledge of where the throttle blades are out.... then again... if its an aftermarket configurable system... why dont you drill your intake runners and make it SFI you'll get better fuel economy and more power than a TBI unit... it'll be more expensive cause you'll need 6 injectors instead of 1 or two depending on the throttle body... but you still need the throttle body for the the blades and such.... i dont know the system you're using tho so you'd have to play with it a bit to get the injectors to spray exactly when the valve opens....also what kind of injector pulse does your box use or is that customizable... ...... theres a lot more to it with injection than carburation...

ok i did a little looking up on your box and it doesn't yet support sequential fuel injection but it will mid 2007... throttle body injection is more simple to setup but definately not as efficient... you'll still need all the sensors i noted earlier, but less injectors, less wiring and less work..... btw if you're planning on running dual exhaust you'll want to run 2 o2 sensonrs or else your computer is going to get a lean signal half of the time and try to richen your mixture on you
