FFX B-727 Gross Weight Problem

[Left_Seat]

FFX 727 is 66K over gross and I can't adjust the payload to within limits without fs 04 closing then restarting.  That's one problem.  The other is the weight, the 727 is about 66k pounds over gross as default.  Can I correct this in the CFG file?  And if so, what entry?

Thanks for any help.
