Narrative:
After taking off from; the mcdu said check weight. We noticed on the takeoff performance print out it said XXX passenger instead of YYY. We aren't sure when the discrepancy happened. I was curious if it happened since I tried to put in the climb gradient per the new memo and it possibly kicked out the numbers if the system isn't up yet. There wasn't a way in flight to see what passenger were invited in a b and c.being new I thought if it was more than 2;000 lbs off it wouldn't generate takeoff performance. When scrolling through page 3 I thought it said 1800 lbs which would have made sense since there were less people that arrived than showed on our prelim. After looking in flight it said 18;000 lbs difference.
