I would disagree. 50 PSI or more from NA nominal PSI OF 1650 at the lower end should be avoided. Same with turbo , eg 1900 PSI. I know a few forum members swear their nozzles are not worn with 300k on the clock or PSI can be off the charts in either direction or no balance between nozzle holders. I am slightly north of 1,000 sets of injectors under my belt and so far all of these claims haven’t panned out. But who knows. If your car runs fine then keep up what you’re doing. For those who are more conservative or traditional, I suggest nominal PSI of 1650 or 1950 and new nozzles at 1700 and 2000 respectively and balance at +/- 25 PSI and new nozzles at the 75 to 100k.
