I'm going to take it easy for the 2000 (already 14% done in 2 days of enjoying it). I accidentally had it kick down a couple times so I have been mostly keeping it in manual to avoid that. Pretend 4000 is redline
It all makes sense for me since it's not all that warm here and I shouldn't push the PSS's/suspension until the roads properly thaw and the frost heaves come down.
