I have a problem with your numbers.
If you have tip tanks you can carry 90gl but your W&B shows only the 60gl in your main tanks (keep your AUX empty), the tip's fuel is FREE weight, that is 180lbs that you can forget about. 90gl @14gl/h should give you 6.5h to empty tanks or 1040nm. As far as I can recall your aircraft has tips or am i wrong?
