Is anyone here running a stand alone engine management system? I want to put on bigger turbos. thats my goal. so ill need to change the injectors still and then get another ecu upgrade?? why? i probably won't be happy with it. Im thinking a stand alone engine management system. Any one have one? and how are they? Which ones do you guys suggest for the 300zxtt? Also are they like plug and play with an adaptor or do i have to spice wires and go crazy? anyone experience this?
