if you plan a cam swap do it then, but it can be done anytime...just has to come off during a cam swap anyway
I noticed my car revs notably quicker from idle to the stall flash point, past that its less notable...
I picked up almost 2 tenths da corrected between the pulley and a tune (my tune wasn't very far off, just a hair rich)

As others have said you can do it whenever and there are no negative effects. If you are going the cam route, it is best to when you install the cam to save money on labor, if you are taking it to a shop. Saving time if you do it yourself.
