nothing special done. hyperprogrammer, flowmaster, and intake and I would'nt call that treaking. Has the factory g80 with 3.42 gear. I don't know why, but this truck just runs stronger than other 5.3 and 6.0 chevy's that I have driven. I have a friend who has had three different dodges, all hemis and three friends with titans and I can outrun them. Have not messed with the toyota yet. I am gonna get around 70% of the torque managment flashed out and it should really fly if the tranny doesn't die.
