Substitute a stock test model with full fuel and drop tanks, ala P-38, hitting all waypoints. Then test the same without the DT's to note differences in the load and consumption. If there's a bug in that soup as well, then its not the air file setup but some gremlin in the sim coding.
P.S. I don't know if CFS2 recognizes this "modern" section in the aircraft.cfg, but a lot of FS cfgs designed with Airwrench contain it:
//0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
engine_type = 0
fuel_flow_scalar = 1
engine.0 = 0, 0, 0
