Disconnect battery?

I just put a cold air intake on my car last week. It sounds nice and runs ok, but as i have posted before seems to be stuttering a bit. When i told my friend about it he told me to disconnect the battery for 15 min. and then reconnect it. I wasnt sure this was a good idea, but i wanted someone else's opinion. Many of the guys on this site have put intakes on their cars so i thought you would know better than me or my friend.
