3G Hemi fuel: EFI vs Carb

Someone has mentioned the nightmare of tuning a MS system. My project is a long ways away, and it will be a 2G HEMI. I am looking into the different brands of EFI. Right now I am leaning towards the FAST XFI for the simple fact that a certain individual has already provided me with a program, that if I remember right, was based on the rough parameters of what my build will be. Another member has offered to host programs on his site, perhaps I could talk to the "Boss" about a forum just for storing tunes?
