I was basing my statement on the premise that the car was running at "optimum" air/fuel ratio and that one wished to maintain that. If one had tuned the air/fuel ratio for maximum power with air, then injected nitrous, there would be no more power. If one was rich and then injected nitrous, the AFR would be leaner so more power but I was thinking the user would not be so stupid as to let it get out of hand.

The cooling effect of the nitrous also helps add power by cramming more air in, but again the energy is released from the fuel so if the fuel is already being burned as well as possible (best power AFR) then there will be no more power.
