fuel injectors
Today I pulled my injector to see which nozzles were worn and along found that i had different injectors of different pressures, A few @ 135 bar and a few @ 115 bar. I know that on many fuel injection systems that the have fuel injectors open at the same pressure. Any advantage to playing musical fuel injectors?

No. It changes injection timing. Ideally, all should be within 1-2 bar of each other.

i have a set of injectors @ 135 bar that need rebuilding. though it was kinda weird and didnt make any sense at all since all fuel injection systems have the injectors open at the same pressure

It is likely that your injectors have been rebuilt in the past. The injector bodies are the same between the non-turbo and turbo engines, it is just the pop pressure that is different. Most shops just rebuild what ever injectors they pull out of the core bin and as a result some may have the wrong pop pressure stamped on the body, but they are most likely still set correctly. I try to grind out and engrave the new pop pressure on the injector body if I have to reset the pop pressure.
