I still say the Holley/4l80E is the way to go, easy to tune, great trans, Awesome support, etc.
Also, it seems less finicky to me. I know if I were to go this route the Holley would be my choice.
One last thing, EFI source makes the gold efi box for the hemi and recently introduced that box with a trans controller for the GM trans. All in one box like the holley. Give them a call and they can explain the system. Much cheaper than the Holley unit and there are several members here who swear by the gold box.
