Im not sure about the 380HP for 35d i have read i one forum a guy had 335d and he has 358HP and 710NM but he said he contacted Bmw and they told them the gearbox in the 335d can hold up to 750Nm MAX. I dont know if its the same on the X6.
Yeah the 335i gets +60HP only after chip
thats very nice
And look what i found about the X6 50i THIS IS ONLY A CHIPTUNE !!
