Not sure who made the nozzles. I didn't think to ask. It has become quieter after about 100 miles. It is certain that these engines have chatter even when operating correctly. I have observed better performance in acceleration since installing the injectors. And it fires up when hot with barely a full revolution - it seems tuned very well.
