Not really. The injectors and rails have been tested to over 30,000 psi which is very difficult to hit (especially with a sensor that only goes to 26,000) the rail also has a relief valve that unless shimmed or plugged won't exceed a certain pressure. My truck has a 30,000 psi rail pressure sensor, but rarely can you tune the truck to exceed 26,000 (the computer just won't let you) you can crank up the duration a lot, but often rail pressure doesn't get cranked up

Do you know the duration that the test goes for? I could see the body or nozzle holding up to that psi, but their is a nasty term called plastic deformation... :|

Well if it's Bosch stuff then the testing is probably extensive and until it's broken. I do think its a good idea to have a rail pressure gauge (my mini maxx has the ability to read it, but I also have the mcc software on my laptop so I can modify 4th gen tunes to my hearts content. Factory setting is a hair over 26,000 psi and that is ONLY under high load/high rpm. Other than that it doesn't break 20k) just saying it's highly unlikely you're going to blow an injector or rail with a tuner. Especially since tuners rarely play with rail pressure. H&s leaves a very good amount of maps alone on their box tunes (from the looks of it rp, pilot, I think they even leave post alone, they leave all but 4 turbo maps alone, and while add timing they use the factory table which looks awful. Worst maps I've seen are by far rail pressure. They're very spiky)
