Depends. A widband would tell you real quick. If its a wet system and you have your jets dialed in and you are still going lean, i would say you are behind on the pump. if you are on a dry system, and your injector duty cycles are relatively low, and your run lean, also pump. either way you need to be on a dyno with a wideband and a laptop.
