550i Dinan increase
I'm interested in anyone that has experience with the dinan stage 1 on the 2011 550i. The car comes with 400 hp and 450 ft and dinan claims an increase to 496 hp and 573 ft torque.
So that is 24% increase in HP and 27% in torque. I dont' know the 0-60 on the 550 i think they say 4.8 sec at BMW, but they generally are quite conservative with their numbers... Also looking for the 1/4 mile times on the non-tuned and tuned 550i 2011.
