I have sac 45's and the tunes I'm running from a vendor are commonly around 17-18k psi and around 20kpsi going up any hill, not towing. When I'm towing, its almost all around 20k+ psi...Does that seem high for just regular cruising around? Will this cause premature wear? If so, then i don't see how having sac injectors have a longer life b/c of the higher pressures needed to run them clean.
High rail pressure and injector wear

So THEFERMINATOR and I both run SACs and write our own tunes, and he will be the first to tell you that you don't need higher pressures to clean up SACs. You can do it with timing and pilot quantity changes.
I run higher pressure than stock on my vehicles, SAC or otherwise, because it increases fuel economy. In theory that will wear out the CP3 quicker, but I've never killed one. As far as I can tell, higher pressures won't wear the injectors themselves any faster.
I wouldn't stress too much about higher pressure. Yours sounds a bit higher than it needs to be even for fuel economy in my experience, but I don't think you're going to have any premature problems.

We can't really tell how high your fuel pressure is based on your description. We would need a log.
