His is a 2002 dually 4X4 crew and he has chipped it. They also re-programmed it. I know it will run close to 130, because I have been in it when he did it. I had mine to 120, no problem there. I think I will run out of RPM before he does and I do not plan on scattering Cummins parts all over the road to see who can run the fastest. I would like to let him know I am around in the acceleration world though. He can tow his 34 Chevy in an enclosed trailer over 100 so easy it is not funny. I think he runs lower on common sense than I do!
