That is what I have been telling myself to make myself feel better about the fact that my N55 feels underpowered compared to my previous N54, that I rarely need to or will be pushing 100% out of my car.

But there is this one freeway on-ramp here where I live, that with my previous N54, I would punch it in second gear, the car would get into peak boost, break traction and the rear end would get out a bit before DSC kicked in. In my current N55 I just can't make it happen, less power, period.

Yes, that did cross my mind a little. My previous 335 had 18" wheels and now these 19" wheels weigh more and are wider with more contact to the road. But I really did not think these wheels would make that much of an effect. Ya think?

You would be surprised on how much an effect wheels make.

It's not the sea turtles, it's the snail, or lack of 1 that is limiting the N55...

Oddly enough I experience lack of power from the sea turtles and their lost lost pals... the snail!
