My advice is let the tires down to the conditions. The softer the sand the softer the tyre. Just beware of excessive speed with low tires, if you try to turn sharp they will roll off the rim. In sand momentum is your friend. If you can see extra soft sand coming line up so you can drive straight through it. 2 wheel tracks are a lot easyier to make than 4. Same goes for driving in other peoples tracks, easyier again. Dunno about the turbo, the isuzu prefers the opposite.:p
