the torque of the n55 is so much more noticeable in this than my 335, it handles a lot better too with the m suspension package
the n55 does have some turbo lag though, my n54 had no problem with this
The lag on the N55 is way less. The twin scroll single spools way faster.

07 08 uses n54, all the others are n55
2007-2010 used the n54, as well as the 1M and 335is. 2011+ used the N55.
