The house edge for this game is high enough so that counting probably won't help.
Not every shoe game can be counted. Baccarrat, for instance, has a pretty low house edge and is dealt from a shoe, but the problem is that the disappearance of cards doesn't affect the play as much as it does for blackjack. As a result, I believe a 3/4-6/7 count works for baccarrat, but you'll need a TC of +18 before the EV goes positive.
In order for a game to be countable, you need all three:
(1) a low house edge
(2) a strong dependence of play on certain cards
(3) knowledge of the history of cards dealt
If any one is missing, you can't count.
