How do drive your vehicle when your ping through mud and gr? would you speed up,or slow down?

I would speed up, you already are going to be slowing down once you hit the mudd which is causes resistance on your front tires.I wouldnt necisarly want to reve it, you want to avoid spining out your tires as much as possible.Say if your doing 25mph , and you see the mudd, gradually acelerating to 30-35 mph (so 5-10) should be more than enought to get you threw providing how long the puddle is and yet still maintaining control of your vechicle....Like said before if you slow down,once you hit the mudd the risistance there is going to slow you down even further and your front tires are bound to sink.It all really depends on how compact the mudd is, incline,how deep and how long the area you are driving.If your doing this for offroading purposes go ahead why not try it out,just make sure you have a winch or a buddy to pull you out if you do get stuck.have fun.Good Luck
