different size injectors/mapping

[Ian (DaOne)]

another stupid question, but at least in the right section

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

will be about the same amount of fuel ian

injector opening time will have been reduced when bigger ones were fitted/mapped
