I have a SpeedHut that has an adjustable calibration, you set the min/max. It seems to be working okay in the 'Cuda, but I do struggle with trusting it completely.

I know I'm good down to about 1/8 tank, I haven't ventured lower. "E" depends on when you can't suck fuel anymore, which is not necessarily the bottom of the tank, at least with an EFI setup that requires constant fuel pump coverage.
