Can a tuner affect the catalytic converter ?

From what i have read the tuner makes the engine run cooler . If that is correct could there be a negative impact on the catalytic converter? Is the motor getting hot enough to make the converter operate properly ? If the converter is not getting hot enough won,t it plug up ? By now those that are running tuners for a substantial amount of time ,would have experienced any potential problems associated with the converter ? Please anyone shed some light on the issue. Thanks Don
