I've heard the same thing about RC engineering, I have to know what machine they are using before I can agree that they are the best.

from what I see in the PDF file and looking at thier machine it's a graduated cylinder measurement system, not very accurate. it's as good as rcengineering. There is only one guy that I know of who can do fuel injectors properly and get measurements withing .10% and he does not use the archaic method of spraying into a cylinder.
