The fuel pressure up VSV is responsible for raising the fuel pressure slightly for hot starts, to assist in alleviating vapor issues in the fuel system when the engine is hot.

If your engine does not suffer from vapor-lock, then by-passing the VSV is a pefectly legitimate solution. Conversely, if you are running an AFPR, using vacuum from the VSV will work perfecly fine, as long as the VSV is functioning properly.

Take care.

Could a rich bog after heavy boosting be concidered Vapor-lock?
