I have efi live. Personally, I dont have the time to do my own tunes. I use LSX power Tuning out of College Station. Lorenz is awesome, and leaps and bounds better experience then I had with blackbear(who we did probably 8-10 gms with). He does all the dirty work, I make small changes ehre and there, minor things, and im good to go.
Really come down to what tuner your going to use, and what they use.
