Spray pattern?

[turbotor]

I did put in new nozzles in my 2 stage aaz injectors yesterday...but a bit knock and hard starting made me test them in my homemade pop tester...

BUT how shuld they spray the fuel??
nr1. fine mist, opening at 147bar (my injectors are marked with 150bar)
nr2. sound like a maskin gun......140 bar.
nr 3 and 4 sprays like a water gun, 137 and 142 bar.

What is right?? :?

Can opening pressure be adjustet on 2 stage injectors?
