The gift Itachi gave Naruto was a book with all the Akatsuki Members I believe. he gave it to him in Shippuden and it was a little black book.
It was some of Itachi power that can be used against Sasuke. This was Itachi's to make Sasuke change his mind, and do something good for a change ¬.¬' But the power that Itachi gave Naruto has not been reviled yet.

It's not sure exactly what power Itachi gave Naruto. All that is known is that Itachi gave Naruto some of his power. You can go to episode 126 and also watch it but in that episode they cut the part where Itachi gives Naruto some of his power. You may have to check the Manga.
no itachi never caught naruto
Although it is commonly speculated by fans to be the Sharingan eye, this is not fact as there has been no idication as to what the power Uchiha Itachi gave Naruto is in the manga to date. What he meant by "I hope you never have to use it," is that Sasuke would never attack Konohagakure -- Itachi asked Naruto what he (Naruto) would do if Sasuke attacked Konoha, to which Naruto replied he would stop Sasuke without killing him. Itachi gave Naruto the power so he would be able to this, or at least have a better chance at being able to.
