When you are getting closer to maxing out the injectors, you are showing the ECU very high airflow values. If you are able to show the ECU the same airflow values WITH the negative correction (for uprated injectors) that you were showing it with the stock injectors, you will run the stock timing.
If you add injectors that are 50% larger than stock (compensating with the AFC), then proceed to make 50% more power than stock, the ECU has no idea that there was any change at all.
Now with 50% larger injectors (550cc/min), you do not compensate with the AFC downwards 50% -- you compensate downwards somewhere around 34.54%. In other words the ECU will see:
(100% - 34.54%) = 65.46%
of the airflow going into the engine.
However, 50% more airflow (or 150% of 65.46%) equals approximately 100%, so the ECU will see the same airflow as before the injectors, and will actually be delivering 50% more fuel to the 50% more air coming in.
Hope that is a relatively clear explaination.
