I wouldn't focus on that one thrust value in the sim. This leaves out how e.g. the drag is modelled and how the thrust relates to the (sim) fuel burn. So it's not like you would just enter the rw thrust values and be a happy pilot. Well, unfortunately not.  :-/ The trick on modelling a good sim flight model is to work around some FSX engine limitations and quirks. By this, the thrust value is one factor in a bunch of.. many. Take the air file for example.

i have been working off of some real take off charts that boeing has and with 19,000lbs of thrust its taking off way to soon and there is no way that in real life that you would cruse at 33,000 feet with only 70% N1 at over 100,000lbs GW with the 737-200

as for the fuel burn i have it fairly close giving Boeing's weight to range charts that they have. the hard part i have is that i don't know how much reserve fuel Boeing was planing for in there range charts.

and with the thrust set to 14,500 it climbs much more realistic as compared to the NGX, it can ezly make it to 33,000 feet Evan 35,000 feet witch is its max alt
