i don't think you're going to see any difference from the engine, but a lot of vehicles are running fuel pump speed control modules now, usually on return-less systems. i think they're doing it because it may extend the life of the fuel pump. although i think it would reduce the load on the alternator. now if you can figure out how to retro fit one on your car, i don't think it would ever pay off financially.
