change the diff oils, i have the mutilator too, great truck but need some fine tunig. I run 7 in the front, 10 in the center and 3 or 5 in the rear diffs, this should make the front grab more and give less spin, the rear is grabbing too much and making the front lift, this setup will make your front pull more, also the mutilator is a truggy, its not really a stadium truck.
