I purchased a set of Nismo 555 (90-93 style) several months ago for my build, several months ago. After many dyno sessions and trying to figure out why the hell im going lean, im thinking these arent really 555 injectors. I have replaced EVERYTHING (fuel pump, fpr, dampner, lines) and I am getting the correct amount of fuel pressure. After datalogging several runs at 18psi the injectors are at 100% duty cycle, def not what they should be. The seller told me that i would find that color of an injector in 370cc style but after talking with bernie and coz we figured out that the new 370s they are selling, are that color. Now I am basically looking for a place (or board member) that can flow test these (and if they are 555s) balance them for me. Thanks for the help
