Jim, if your wanting to run low impedence injectors on a stock EEC then get the Acceleronics Low Impedence box. Brad @ Total Performance said he is stocking then now. http://www.acceleronics.comRacer LX said:DOH!! They are, arent they? My bad. But actually when I posted my question, I was thinking more about 72# and 83# injectors. Sorry about that, I wasnt real clear there. But anyway, I'm collecting parts (slowly ) for a 351 build up I want to do, and am thinking that I'll probably need at least 72's for what I want to do. So the question remains, what are folks doing with running big injectors, short of going to a FAST or DFI system?
