The sage of six paths was an imperfect jinchuriki, Hence his power was decreased by likely 3x. As you can see here

he stated he didn't know their names when they were inside of him as one evil mass(Ten-tails), Now that they are seperate & good and now naruto knows all their names, When they combine again they will become the ten tails but this time all the hatred will be gone and naruto will become the new sage as hinted by the previous sage himself. Naruto will lead them down the right path he spoke of and he will become the perfect jinchuriki of the ten-tails. His power will far exceed the previous sage. Just you wait and see. Naruto will show you the "true power" he spoke of...
