Hypertech or Efi live for fuel economy ?

[buck0000]

Hey guys i was wondering if the hypertech max energy tuner will give me more MPG than efi live can ? I realize that alot of that depends on the person making the efi live tunes. But from the tunes that you all have seen and run which is the better way to go for fuel econ. I realize that efi live is the better bang for your buck as it can do more but i just wanted to know for the sake of MPG.
Thanks guys and feel free to correct me if im wrong im still learning bout all the dmax stuff cause i was a cummins guy

you pretty much answered your own questions there man. Beyond being a good tuner for MPG, EFI is a great diagnostic tool to have for these trucks. I use mine for diagnosis as much as tuning.
