How would you verify the pressure if you don't test them?
If it was me... I would just save up and buy a whole new set of injectors. Because like said before if you just switch tips how would you know they are functioning correctly without pop testing them? This is the only con I would know in your situation... uncertainty.I can clean up all my smoke and it feels like power drops off at a point now with my 5x14s and 024s, so i feel like a little more fuel is in order. I was thinking of trying to sell or trade my 5x14s for 16s or 18s but it just hit me that i could buy new nozzle tips for ~$300 and still be able to go back to the 14s if i wanted. Would i have to get the pop pressure reset if i put different nozzles on? They are currently at 290bar and have maybe 8-10k miles on them. Would there be any cons to doing it this way? Thanks
Essentially you have a pump that squirts fuel (or something else less toxic) into the injectors. When the injector squirts a pressure gauge tells what the pressure was. Then to adjust the pop off pressure you add or subtract some hardened shims to make the internal spring act sooner or later. It is a bit more complicated but that is essentially what is done. If you search you can even find a home made pop tester thread online.how exactly is pop pressure set on them? just wondering
