NA10X injectors in 91 Jetta?

there is actually an advantage to running higher pop pressure injectors. they atomize fuel better and give you better power and mileage. early 1.5 engines called for 1.15 mm of advance. ive heard that they had 180 bar injectors.

interesting-I was testing some old injectors that I had picked up from something, and they popped at around 2500 psi-much higher than the others I was testing-maybe they were from an old 1.5 dasher engine I'd swapped heads on.

My Bentley's says the ME engine injectors should be between 130 and 138 bar.  what's the conversion between bar and psi?  I've never had to deal with it before I started playing with these injectors.  Maybe I can detune the NA11X injectors with different washers-since I have several that are too high a pop pressure for my use. any idea what the timing problems would be with the higher pop pressure?  Would car even start/run?  it's been too cold to do much outside where the car sits so I'm brainstorming ideas.

1 bar = 14.5037738 pounds per square inch

I imagine one would run, mine will start and run anywhere from .85mm to 1.20, and there isn't a screaming difference between any of them either, go figure.  Seems to me higher pressure and more timing would be better, but what do I know.  I guess the theory is the higher they pop, the longer it takes to reach that pressure when in use, delaying the injection even and therefore timing is off.  Seems like you ought to be able to use bout any injector is you could come up with some math to get a good timing figure, or trial and error it.
