Say a guy is choosing fuel injectors...obviously output is the most important and impendance but what else? From past experience I know some items are only made by a few vendors and everyone else makes pretty stickers to put their name and price on....is there really a difference or does say seimens and delphi make nearly all the injectors out there and Fast, Accelle and Venom just relabel them? I see this all the time in electronics, just curious as I shop around.
Also impendance...I know what it is, but how does it apply to fuel injectors? I'm using an Accele DFI but curious about how it works as much or moreso than just what to use...I'd rather understand it than just order a part
Thanks,
