ls1 injectors on 5.3 tune

My tuner is tellin me that the ecu doesn't need to be tuned for the ls1 inj. He says the ecu can compensate for the slight change. Is this true?

Re: ls1 injectors on 5.3 tune

What are the flow differences between the two?

A better question, it only takes a few seconds to change the value, why not?

Re: ls1 injectors on 5.3 tune

it should be "callibrated" for the correct lb/hr injector. otherwise it can't control the fuel efficiently.
