PiMPxs is high impedance only. Injector selection depends on how much power you plan/hope to make (not necessarily just right now but in the foreseeable future). Since I don't have that info I can't select them for you but our injector charts show approximately how much power each size will support for V8's. In general you don't want to size the injectors so they are maxed out at your power level but rather have some room to grow. So if you want to make 550hp and one size of injector supports 560hp and the next size larger supports 625hp, get the size that supports 625hp. If the smallest set listed supports your power goals with room to grow, get those.
