I'm not positve what you are trying to say, but here is shot. If you are using stock injectors, you dont want to alter the MAP readings at all. We get more fuel under boost with stock injectors by this: When we go into boost (0+ psi), the ecu sees a map voltage of around 4.5 volts( it wont go any higher if you have a Missing link, or VC1/2). The ECU gets close to around 80% injector duty cycle. Duty cycle stays there as boost increases, but we get more fuel by upping the fuel pressure at the injectors. More fuel pressure equals more fuel spraying from the injector. Make sense? Or are you asking something different?
