This is how Naruto maintains his current Sage Mode, the science of it anyway:
What Naruto does is, he keeps his Spiritual energy(chakra), Physical energy, and Natural energy in a perfect balance.
And the energy that results from that is called Senjutsu Chakra, that is how he acquires Sage Mode.
Before, Naruto had to take in Natural energy in proportion to his own chakra, or he would disturb the balance and the Natural energy would take over his body, turning him into a frog.
Now that Naruto owns the Kyuubi's chakra as well, and he can convert it into his own chakra at will, Naruto's chakra reserves have increased a 1000 fold!
Now Naruto can take in a lot more Natural energy, and I mean, A LOT MORE. Since Naruto has to keep the balance between his own chakra and Natural energy in order to create Sage energy, Naruto can now take in Natural energy equal to his own Chakra + the Kyuubi's chakra(which he converts into his own).
Which will result in an almost infinite Sage Mode!
The strongest Sage Mode.
