i've been playing arround with diffrent Borderlands 2 editors and i found a way to mod the character lvl up past 1200 and the gun damage aswell. if you want me to do this with your save send me a message with your save file. P.S the guns in the photo's are not mine i only changed the damage.
i would love the gun damage, but without raising the level 50 of my characters..don't think this is possible yet though
