I'm modding a forgefiend to compensate for a powerful party. Since it has the Earth subtype and a burrow speed it gains tremorsense.
Earth Subtype
This subtype is usually used for outsiders with a connection to the Elemental Planes of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock. Earth creatures with a burrow speed possess tremorsense.

My question is since the sense isn't listed in its stat block, what do you feel is a fair range for this ability? I just bumped it up from a CR 10 to 11.
I was thinking 60ft since that's what a CR 11 Elder Earth Elemental has.
