Even with a EFI calibration you still get some "wetting" of the runners prior to the intake valves.
The Calibration guys do the following:
A Throttle blade change, read by the TPS sensor, tells the calibrator whether to add or decrease the pulse width to the injectors for that event.
If fuel is pulled from the runner walls or plenum, the calibrator has the injector reduce the pulse width for that series of combustion cycles, until the HEGO says the air/fuel is where it needs to be for Stoich operation again.
The Government requires running at stoich all the time.
