Todd,

I’m going to make this point for the purpose of helping educate others here. Your suggestion of changing the Secondary Injector Scalar (which may be a misnomer) is simply to get the same “effective” PW as u would using two 21# injectors. Am I correct?
I’ll bet you will still need to visit the VE tables.
Second question, would that not negate the purpose of the 24# injectors in supplying fuel to a larger displacement motor?
BTW, I say the Secondary Injector Scalar is somewhat of a misnomer because the ECM does not drive the secondary injectors. The primary injectors signal the secondarys in terms of PW while the ECM simply energizes the secondary injectors thru the secondary relays.
