New Fuel System: Questions!

[Daedalus]

I just purchased a turbo fuel pump and 390cc injectors from a turbo A/T eclipse.

Can I install these parts without running fuel managment? I thought it would be plug and play... am I incorrect? (Under 400CC, ecu can control?)

Thanks for your help!

you need some sort of fuel management, like a S-AFC. if you have bigger injectors, your fuel pressure regulator will try and keep the pressure the same as it was, so your injectors will be delivering more fuel than needed all the time. especially at low speeds
