You can run any fuel pressure you want to within reason. Obviously, there are limitations on the low and high ends where the injectors will no longer function.

The only thing that is important is that you know what the injector flows at your new pressure. There are a couple of ways to do this, either using a mathematical formula to figure what it SHOULD flow, or, have one of your injectors flow tested at the new pressure.
