3x2 FI system
I have a 4 barrel Fitech system on my 330 inch Desoto motor. In this system all 4 barrels open together. Mine is a port injection system that I have built up and it works fine. Initial off idle opening is not touchy. It does not have injectors in the throttle bores.
In the TBI systems they need to open all at once because all 4 barrels have injectors in them.
