Is it possible to drop temps too low?

Is it possible to make intake temps too low to where the engine runs worse? (I.E. By shooting the IC?)

If you don't compensate the dense intake air w/ additional fuel then you could run worse. The MAS should pick up the additional airflow, but not the huge temp change. ECU calculates injector flow for the stock system, so it doesn't know that the intake air is so much cooler. You have to tell it to do something to pump more fuel.
