    Rising rate or not

    Is it best to use the refference line for the rr or not which one is better for performane
    Or does it not matter at all. And would there be an rpm increase or just the same either way.

    It all depends on what your fueling needs and AFR's are.

    Without the reference line attached it's just an adjustable fuel pressure regulator, pressure stays where it's set. Withe the line attached it increases from the set point 1 pound of pressure for every pound of boost starting from the onset of boost off the charger. It will also decrease pressure a bit when the engine is under vacuum (no boost).
