I had A 2009 335i for 3 years and now E90 M3. When driving the 335i (N54), you almost convince yourself there is no lag because it is a quick car...until you jump into an NA motor. Lets not kid ourselves, the lag is there but its not horrible. I actually liked that jumpy feel...lol. Hopefully though, it will be "cured" with the new M3 but only time will tell. I think they will do something to minimize as much as possible but we may get an artifical feel...just my 2 cents.
My questions are:
Is there a noticable improvement with the N55 w. respects to turbo lag
How does the new M5 turbo lag compare to N54/N55
