Like in the following: Compressor maps - examples and explanation
You're confusing the difference in flow and PSI and what each means in terms of getting more air into the motor. If PSI is kept the same the motor could not care less about an increase in flow because without the increase in PSI it is not going to see an increase in the amount of air entering it.

Again, a larger compressor can create higher pressure levels but when run at the same pressure level as a smaller compressor its only advantage is that it is running at a lower percentage of maximum output.
