You sure?
The spec says:
"By default, UTFGrid operates on a 2x2 grid. This means that the maximum information resolution for a 256x256 tile is 128x128"
(Same on the 1.0 spec)

Every one I've used is done with resolution 4, so may just pull anyway.

Yes, that's out of date: 4px/grid has become the default but the spec is not updated. I've started a 1.3 revision that refs this ticket and corrects the resolution figure. ( mapbox/utfgrid-spec@984bdcd )
