well my buddy with a 5.3, 4.11 gears and a bigger cam gave me run today and I felt like I should have been able to take him.

My truck has 3.73 rear and 285/75/16 mud terrains, the only thing I can think of is my the size and weight of my tires are slowing me down, check out my mods in my sig and tell me what you think I should do?
