New Game+ ending

I've played the game all the way through three times now, and each time have failed to make 100%. I lost .6% or something each time, and can't find it with each playthrough. In the end, i'm fed up with trying, so i got a friends 100% new game plus file, and am doing a super quick playthrough. the thing is, he spends the summer in another state, i don't have the number. and he said something about "you have to talk to this guy in chap 3" or something like that, to view the perfect ending. does anyone know of this so i don't miss it in my ultra quick playthrough? i really don't want to do this a fifth time... it's a good game, but Jesus.... 5 times?

I sent you a PM about it.
