Yes...
I want more power of course.
I want to run an intake (for sound as much as anything else) and therefore don't want to run the risk of running lean if the ecu demands more fuel based on the increased air intake and the pump can't provide etc.
Simples :D
it probably won't make that much more power, but what it will do is fatten up your mid range torque so that would be worth modding for.
