Launch control is a gimmick anyway in cars in this class.
I dont think 550i is going to be faster than S6 even with such upgrade
In fact, i'd be surprized if it even catches S6
I just bought one and this thing is a beast
It is great deal faster than current 550i in any speed range
I've had pretty extended test drive in 550i, before i bought my S6, so i can compare
