To tell you honest truth, most of my riding on that sled this year has been in powder, so I have used the skis for turning very rarely so far. I have noticed that on the already tracked up stuff it seems a little harder to stear, but then on the trail is is fine, so I have not messed with the shock settings at all.
The PSI settings would be what ever they were at setup. I suppose I should really check to make sure that they are still at that level, but I guess I have not noticed a change in the performance of the sled, so have not checked them.
Sorry I could not be of more help!
