I have a buddy that has a 02 3500 cclb drw 4x4 with intake exhaust and a efi autocal spade and our '99 6.5 dually at work is faster than it :nail:. Problem is when you run it WOT it takes off and then falls right on its face. Took a couple data logs and sent them to duramax tuner and they said that it was only getting about 3k-5k psi of rail pressure instead of the demanded psi. Question is, is the cp3 gone out or is there something else we should be looking at. Fuel filter has about 3000 miles on it and that didn't help any at all. Thanks in advanced for any help.
