Last time I cooked T-day dinner I didn't stuff, cooked didn't add much (if any) water and followed the directions from the turkey co. to a T, unfortunately the damn thing came out dry, overcooked it and I had it in for the minimum they suggested. Should have taken it out half an hour early, and mine wasn't even fully thawed (noone told me takes a day to thaw, woopsie.)
I'd take peoples' advice over Butterball, those companies don't know jack. So many environmental factors like elevation and type of oven.
Go to Outback.
