Correct, around 14 to 15psi on pump gas, and much lower on E85. When my car was equipped with the Kraftwerks kit for a brief period, we maxed out the stock injectors on E85 on the stock pulley (peaked about 10-11.5psi at redline).
I would like to point out, however, that the stock fuel pump actually has quite a bit more leeway. The injectors need to be upgraded long before the pump does.
