I don't see why they couldn't have just cleaned the old ones out and then checked the balance rates. Also make sure they do a return rate test on them, and if they don't know what that is they shouldn't be working on a common rail injected engine. The injectors do 2 jobs, the first is to inject fuel and the second is it has a metering circuit to return a small amount of fuel to the tank to allow lubrication and cooling to the injectors. The second part is the return rate, and is one of the number 1 problems to cause a no start in a common rail engine.
