Questions about Silver Lake Sand Dunes

Greetings to all Bronco loving owners who have taken their vehicles to Silver Lake Sand Dunes. We have a Wildtrak and are heading to the park this weekend. I have run this bad boy thru all sorts or dirt, but not an environment like the dunes. A couple questions to give me a baseline.

What tire pressure?
What mode?
Did you shut off the traction control?

I plan on really experimenting with the vehicle, just looking for What did you do from folks who have ran their Bronco at Silver Lake...
