BimmerWorld does 74ft lbs for both 12mm and 14mm studs. Still undecided, but I plan to stick in that range 80s,90s.... I know there are recommendations as high as 115 ft lbs.
fwiw, 105 ft lbs on the front 14mm was problem free for me for a whole year that they were on the car.

Core4 has their own recommendations for the press-ins.

EDIT: Tom was talking about the technical aspects of why 14mm use higher torque, but I don't remember the reasons.....But, definitely ask him. He's happy to talk about that stuff.
