That can cause your ECM to never go into open-loop operation at WOT, and you will likely run lean at that point regardless of how big the injectors are, as the ECM will still be trying to regulate the A/F ratio via lamba control. Been there, done that.

These computers are more sophisticated than that. More than just the MAF signal is used to determine fueling, and the MAF signal is used for more than to just set injector duty cycle.
