Mine never comes out of Insane mode, even in the winter! I'm no Ms Daisy, believe me
My commute is mostly 2 lane rural highway, so 110 km/h, with very little opportunity to punch it (just one turn really, and the occasional pass). In summer I also pumped up my tire pressures a bit, up to 45 instead of the book 42 when I needed to make a trip that stretched my range. Made a bit of difference, so I kept them there afterwards.
I'm also on 19s, not sure if you have 21s or not?
Oh yeah, to stay OT, winter tires good. Staggered winter tires bad.
