Flow is what makes power, not pressure. Upping the pressure only gets you so far with an injector, after that you need more flow and bigger injectors.
Doesn't matter. In both cases, the rail is supplied with regulated pressure, end of story. Having also owned a Buick GN, there is no real difference. the bottom line is that the regulator will control fuel pressure the same way in either case.
