even with his cheat codes minato still beats him,how can itachi cast tsukiyomi or amaterasu on minato if he'll be always teleporting?Itachi outbrains him, and sorry what power? Rasengan and Flying Thunder God? kid please. Itachi laughs Minato to death.
itachi can't track minato with sharingan since it's not physical movement it's teleportation.
another thing itachi can't keep his plot armour susanoo forever,i doubt he can even keep it for 5 minutes,while minato can teleport as much as he can.once his susanoo is down he's dead.one kunai on each side and he won't know what hit him.
and i bet you think he can use amaterasu and tsukiyomi a lot,well newsflash he won't be using more than 5 before he's out of chakra.
