ok, I had my car mapped before with 550cc injectors (apexi power fc in classic impreza)
now i have 740cc injectors, and they have been mapped.
but from going from 550cc @ 3.5bar @100% duty on the commander
TO
740cc @3.5 bar @ around 70% max
would i be using more fuel as they are a bigger injector, or should it be about the same as they are not working as hard as the 550cc
am running the same boost etc
thanks
ian
