What is happening on the other side i.e. how much additional fuel - if any - is being added as the throttle is opened? (Analogous to the accelerator pump in a carb.)

It's port injected. Only the new BRZ and 2015 WRX are direct injection
How should I test if any additional fuel is being used when the throttle is opened? (I have the TORQUE APP and MPGuino)
