So then she surpassed Tsunade in strength. As for Tsunade healing Shikamaru, he was going to die regardless until Naruto's chakra saved him, Tsunade came and healed him before Sakura got the chance to after the Shikamaru's cloak came back. Sakura had to heal him from near-death but Naruto's chakra was already doing that by the time Tsunade showed, making her job significantly easier. Sakura also has comparable healing feats during the war.

Remember that even back in part 1 Tsunade saved Naruto by the skin of her teeth because he was already so close to death.
