I have no idea. I used to do it myself, we have a machine here but it is in a shed out back now they took it out of service. It would cycle the injector in the ultrasonic then flow test it with calibrating fluid in "graduates" like a flask in chemistry class.
I've seen them stick open for the first 100 cycles then start closing up, I've seen them stick closed for the first 100 cycles or so then act normal. I've seen them never open, I've seen them stuck open and I've seen them drizzle. So many things can happen to injectors. Almost worth it to buy a new set.
I can get a set of 8 that are already rebuilt off of eBay for 100 bucks. Might just have to do that
