Cant see sh!t on that vid. I got 2 buddies one with a 04.5 cummin, usual mods with intake, straight pipe, predator stacked with a dr. performance, some other mod done to the fuel pressure too, but on 35's with a 4" lift, truck was never ran at the track, but me in my L i would instantly pull on him. Here you can see some videos of it, http://www.youtube.com/user/jeffreycastgsx. Another has a 06 2wd crew duramax (only vid of that i could find http://www.youtube.com/watch?v=T78k0YXwkqw) , only mods are edge, intake, straight pipe, his PB was 13.7 on stickies, he would slowly pull on my SVT, and he would also rape the cummins. In the end, my buddy with the cummins sold the cummins, and now owns a 03 LB7 duramax soon to be efi live tuned.
