Any App or Tweak to lower Torch backlight below the minimum "0" setting?

Does anyone know of an app or tweak that I can use to dim my Torch's backlight below the lowest level "0"? ("0" backlight brightness level is quite the misnomer by the way) I regularly use my Torch at night for Nav and even at its lowest backlight brightness setting, the display puts out light levels that reduce my view out the windshield. Can the Torch's display be dimmed at infinite levels from brightest to completely dark or at the least below the "0" setting?

I have tried changing every display setting I could find and just can't get it to the lower light level that is comfortable at night. Thanks in advance.

It's the same deal with the Bold and the Curve... If you're actually in a dark or darkened room you cannot set the display light level low enough to balance well. Like you say 0 is not 0 in this case.
