That is usually standard pressure that injectors are measured on and a good place to start. Fuel pressure will have an effect on your fuel mapping so I wouldn't experiment too much without some AFR readings or you could cook it.
I run 52lbs on mine but have gone through the fuel map and tailored to my specific needs.
