Pop off pressure changes.

[RonA]

If a fuel injectors pop off pressure is set at "x" and you change it in small increments both plus (+) and minus (-), what changes in performance do you see. Does it start to get smokey as you decrease the pressure? Will it run cleaner as you increase it up to the point where they start to miss fire from not opening?

Good question, I'd like to know for sure as I have ideas, but I leave it all to my injector guy as he has it in one sock!

I found a pop off pressure tester for sale. I costs about the same as a good turbo. I sent them an email to see if it can be set up to test both 12 and 24 valve injectors. Might be a good way to answer this question. Just had new nozzles put on my old injectors. Going to run about 300 dollars with me supplying the nozzles and injectors. A little playing could get expensive rather quickly. If the device will do the job I think it would be interesting to play with.
