I guess the only way to tell if your injectors are popping at the right pressure is to do an injector test. If they're not popping at the right pressure, the injectors need to be rebuilt.

Or if they are giving a poor spray pattern, then you need new nozzles, is that right? Or do you just clean your existing nozzles?
At what point do you buy new nozzles? How do you know if your existing ones need to be replaced or not?

Has anyone noticed that their new nozzles gave them more power since they spray better?
