You can get any programmer you want, but why would you want to get away from EFI live? You get a good tuner for EFI an it’ll literally be made for your truck an it’ll run the best
It all depends on exactly what you want the truck to do. If you just want a little bump to spin the wheels at a stop light then any tuner will pretty much do it, if you want to get the extra power an have that extra itch of wanting more an knowing you’ll add bigger injectors/turbo an really look for a higher hp/tq number then EFI is what you want
