With the monark nozzles does your car run better?

I'm not so sure loud always = more power. It still sounds like a diesel but it's smoother and more efficient. What you get when replacing worn out injectors = wide, stringy fuel jet, opening too soon even when the static timing is correct, inconsistent fuel delivery even when the IP is metering properly versus concise, controlled fuel jet delivered with good atomization consistently opening at the correct pressure for the correct duration. It adds up to the engine getting fuel the way it should. I need less throttle pedal to accelerate, it went from light smoke on start up to none at all and starting is just a tad quicker. To answer - Yes it runs much better but if your injectors test out OK I'm not sure you will see as big an improvement.
