Default Injection System

My system is a hilborn injection system. How important is running a high speed by-pass valve?

It will definately run better on top end with a highspeed leanout, due the nature of the mechanical pump putting out more pressure as the rpm increases, not just my opinion but hilborns also.

Zip.
