You do know most of that mod is a major bugfix, right?
I tried the AP ammo fix, worst fucking decision ever. Frank Horrigan was invincible to small guns.It also seems to change a lot of shit, which isn't very good for someone who doesn't have a clue what they're doing like me. E.g. putting a hard lock on Vic's shack door so I can't even complete one of the first quests in the normal way, and therefore have no fucking idea what to do or where to go. Maybe it would be good fun for a second or third playthrough, but not the first.
I did, however, install the unofficial patch, which also seems to fix a lot of stuff without introducing silly changes everywhere.
