Go to the university and go to the class - piloting. Raise strength a certain amount and open Cheat Engine. Once you've killed the trainer for your stat, multiply the new stat by 8 and type that into the cheat engine box and search. Raise the stat again and kill the trainer and with the new stat, multiply by 8 and do the next scan of it. Then click the only one left freeze it as something really big divisible by 8 such as 80000. This isn't permanent and will stay only until you log out. The value you change it to isn't the damage you do, it's your strength stat, which increases weapon damage by a certain percent.
