I bought this Crew Cab, LT package truck new; now it’s sitting at 49,000 miles. Modifications include tuning by Duramax Tuner, an S&B Cold Air Intake, ATS Dual Fueler with Sportsman CP3 Pump, Stealth 64 VVT Turbo, DT 750 Built Transmission by Duramax Tuner, Cognito Stage 4 Leveling Kit, Cognito Tie Rods, Cognito Heavy Duty Swaybar and end links, Fass 150 Lift Pump, Beans Diesel Sump, Edge CTS2 Display, MA transmission brace, MA PCV Reroute, and Royal Purple Fluids. In the future I want to add a twin turbo and 60 percent injectors. I use it for daily driving, drags, and heading to the Silver Lake sand dunes. It's my first diesel and I'm having a blast building it. Right now it dynos at 615hp and 1,200 lb/ft of torque with all emissions intact!
