Vf clarification

MmmBoost

DDS Performance
so, i had been messing around with my safc now that i got my wideband. a situation that i encountered was that if i got a good tune down for wot, as long as i had part throttle changes it would start making the afr's jump all over the place when i did wot runs. i have since then disabled all part throttle correction, and the afr's at wot have been very stable

clarification: is that all that satisfying vf means? i have the vf output of the ecu plugged in to one of the extra sensor wires of the safc so i can monitor it, and i am around 3 volts almost all the time. as far as i know, thats what it is supposed to be, but do i need to do any other tuning in general before tuning for more boost?
