Nope, that is how much I put on him before I let off, at least a 1/4 mile. From the time he pulls next to me, I leave him sitting there, in a few seconds he is so far behind its not even funny. I am sure he had a governor still on the truck and was stuck doing under that.LOL Everyone doubts the 4.8, when I get tired of it lifted, I will drop it back down and then offer whoever wants it the chance to run it down the track for themselves. I welcome anyone that wants to check for additional mods to inspect the vehicle at anytime you want.
