OK Todd has a calibration mod that can be used in a stock motor that can be used to test that. It pulls the secondary throttle blades open and goes 16 injectors on startup. It changes nothing else in the calibration, run that back to back vs a stock calibration and see what happens.
In the stock configuration going WOT does not enable an instant 16 injector secondary's open mode there are a series of check points that have to be met before going to the next calibration configuration and into the final PE table.
If not that then its cam design? Ie the lower rpm profiles are such that its engineered for a leaner mixture and it gets more aggressive as the rpms elevate with a transition point where the motor is slightly under fueled.
Its got to be in the fueling, calibration or cams.
