After playing with a friend, we both had the mod installed, i have some things to show you, that hopefully may help you.
We played on difficulty 6 on quick.
We used following versions: (i know thats now 2 patches behind, but it still may apply)
Civ IV Diplo: 4-15
Comm Balance Patch - Comp-Files: v1
Community Balance: v13
Community Patch: v66
CSD for CBP: 5-2
More Lux: v155
1. The AI was behind us/keeping up with tech but we didnt focus on teching
-> Thats a BIG improvement, with no-mod the AI in team games fall behind very quick
2. There was no war, even though location and military power should have forced Japan to murder is neighbours (Inca and brazil were very weak on the military level)
-> this may be a problem because we had teams of 2?
3. ROADS! I was so confused when i found out nobody likes roads! Here are some screenshots:

4. After a citystate was conquered by barbs, it was rescued by another city state, it was puppeted (just an information)
5. Gold was much better for all the civs, Japan was highly negative but had a huge army (standing around). I have no clue why Inca and Poland are so negative, but it may be related to the unwilligness to build roads?
If there are any other questions regarding this game, just tell me.

Unreletated to this game, in a previous one, we also had Inka in our game and they never expanded during the whole game and had a horrible small city, no clue what was going on there.
