Max's OBJ importer is designed to scale objects when you import them. There is an option to disable the scaling though, see here:

The new built in one does not do any scaling.

Looks like your polygons do not have welded points. You'll get a result like you show if faces have their own individual vertices where they touch rather than faces sharing a single common vertex.

What are you using to make the OBJ file? Can you post it or e-mail it to me at moi@moi3d.com ?
