We had a machine at TAFE and could do our own, the teachers said that 9 times out of 10 there was nothing wrong with them and no measurable amount of muck came out of them, however if you're putting injectors with an unknown history into a performance application, it's definitely worth doing regardless.
Good info. I had no idea what the process was.
