is there a way to make it start off faster? and go faster? and what are some good setups for going through deep mud and water on the 2x4?

 

High lifter monster performance kit will give you the power, you also need some mud runners or 589's on the rear to go through the deep stuff. Also if you get into deep water or mud, put your knees on the rear of the seat to transfer the weight to the back tires. Also hit whatever the terrain is with enough momentum. The 4x2 will go through the mud as long as you stay on the gas. Next time you get to a sticky spot; hit it with 2nd or 3rd pinned.
