People with ridiculous levels of chakra can apparently use that to become stronger, like a lite-version of the Eight Gates. Naruto in Kurama Chakra mode could move extremely fast and was extremely strong for instance, just because of the chakra.

However, it appears that this isn't a sliding scale. Above certain levels of chakra, it suddenly seems to matter.

Also, the Raikage use their lightning chakra mode to be fast and strong, so it's not all natural.
