high rpm vs low rpm

Hello all, I'm trying to figure out my strategy for modding my '94 F150. A lot of mods seem to enhance high end power at the expense of low end and vise versa. Unless I am mistaken, some items that fall into this category are exhaust (long tubes vs shorties), timing, and cam profile. Now my question: Is it better to enhance high end or low end if one is trying to get better fuel econ? It seems like the low end would be more beneficial for getting going from a stop and high end helps more at maintaining highway speeds. I imagine it'll come down to whether I drive more city or highway. I can't decide which is more important though, high end or low end, because the truck burns plenty of gas on both! advice plz
