I've noticed that on the second play through the drops are of higher level and color.
Also there are weapons that are the same as the first play through that are of higher level in the second play through. I'm gonna take a look sometime to see exactly how to change the level of the weapon. I couldn't really find it through the method syntax posted.

If you use a good Hex editor and you look through the info carefully it's actually really easy to find. Upgraded stuff very quickly that way. My question, is there a way to up the stats w/o the required level. That would be nice. Not a big deal since it'd make everything too easy, it's more of curiosity.
