Same box but maybe internal differences? No clue as i would assume the gear ratios are different between the tire sizing, weight and final drive. Loved the 6F50 in the Edge. Did exactly what you needed it to do without much fuss and if you wanted to change your own gears, slap it into Sport mode and let it eat. Also handled a boatload of power without overheating anything. Held both a 93 and E30 tune on our Edge Sport without a single issue on multiple long road trips with my heavy foot just full throttle out of every toll booth.
