The high-horsepower Duramax is fed by Dual Fueler CP3's from PPE, which were modified by Industrial Injection. In addition, a set of Dynomite Diesel Performance injectors flow 100 percent more fuel than stock units.
Fuel is delivered through a set of Dynomite Diesel Performance injectors designed to flow 100 percent more than stock. Dual Fueler CP3 injection pumps from PPE and a FASS fuel system provide consistent fuel to the injectors. PPE tuning, modified by Chad using EFILive, dialed the truck in electronically. The fact that EGTs reach 1,700 degrees on occasion confirm our belief that his Duramax is generating some serious power.
The factory Allison transmission was built by Sun Coast, and features a billet rear tail housing. Up front, a Sun Coast 1055 triple-disc converter transfers power from the engine and gives the turbo a chance to spool and light effectively. To play it safe, Chad decided to use a transmission blanket, which is required on all competition trucks that exceed 4,500 rpm. The factory suspension and shocks were retained, but traction bars and blocks were added to limit breakage.

Although Chad's engine spins what some would consider to be a low 4,200 rpm while pulling a sled or drag racing, he decided to wrap the Sun Coast transmission with a tranny blanket for added safety. |  While Chad and the rest of...  While Chad and the rest of the Empire Diesel crew were new to running this truck down the strip, it was obvious they'd hooked to a sled a time or two. |  Although Chad pulled out the...  Although Chad pulled out the rear seats, the interior of his Silverado hasn't been altered much. Most of Chad's time in the cab is spent watching the pyrometer, which usually exceeds 1,600 degrees F. |

Aside from taking 1,100 pounds worth of weight off the front end, Chad changed little on the truck between Saturday's sled pulls and Sunday's drag racing at Scheid's Diesel Extravaganza. Even the trusty 35-inch Interco STS pulling tires were retained, which got him through the eighth-mile in 7.81 seconds at 93.8 mph. |  The factory 11 1/2-inch AAM...  The factory 11 1/2-inch AAM rear axle and 3.73 gearing get the job done on both the dirt and the pavement. |
