with a 2wd truck, I doubt you'll ever beat a 4x4 truck with a similar amount of power. A 6.4 with any spartan tuning is going to be tough to beat, especially when he has 4x4 and you don't, not to mention the 310 tune. You can have all the power in the world but if you can't put it to the ground then it doesn't really matter.
You'll probably just have to accept defeat and move on with this one. I doubt you'll ever beat that truck.
If you can get him to race you in 2wd, then at least you'd have a fair race. But with that much power it comes down to driver skill and throttle control more than pure power of the trucks.
yes very well put, okay well i had a thread on here about trac bars, but im just gunna u bolt my overload to the rest of my spring pack and hope that gets me more traction, my dad has an ext cab 09 lmm dually with ppe hot+ on lvl 5 can that beat him? he also has 4x4.
