I don't mean to high jack this thread but since we are on the subject of injectors. I took my injectors out the other day and all of them have a hand engraved date and 44.4 on them. My paperwork with my car says 50 lb injectors although I can't find a part # to confirm it. I'm thinking these were a matched set and maybe flowed 44.4 at a certain duty cycle? Does this make sence to anyone?
