Im on a phone at the moment, but what you are gettng looks fine to me for DNSI.
Remember with DNSI you're relying on the normal map for bump and normal maps dont really change the bump, they use light and shadow to outline detail so unless you exagurate the normals it will only be subtle, for real bump you need to move onto height mapping which gameguru doesn't officilly do.
Also, make sure your entity setting in the tab tab menu is set to highest to see the full effect of the normal map, the lower the setting the less the normal influences the model.
