My 2004 Chevy Duramax 2500 HD is an extended cab with a short box. I recently repainted the truck, and installed new cowl hood fender flares. I keep my truck very clean, and currently it posts 629hp on the dyno. Since I first bought the truck I have built a 5-speed Allison transmission to handle increased horsepower through the addition of a 4-inch MBRP to an 8-inch stack. I also have a turbo back Stage 5 EFILive tuning with a Diesel Mafia Performance 66mm turbo and ARP head studs. I have added bigger intercooler pipes, an HSP intake, FASS fuel pump, Fabtech tie rods and leveling keys. The truck sits on 33-inch 13.5 Mickey Thompsons tires on 18s gear rims. I would like to do a twin setup injectors and injection pump, and build the bottom end on the engine in the future. Currently, I use my truck for track pulls, dirt drags, dyno competitions, and, being from Idaho, farm work. My truck has been really successful in local events. I have competed in three drag race events, winning first in the single class twice (once at Bully Dog Days). I have also tractor pulled with my truck five times in 2014, and was in the top five every time.
