Tuned 2021 Duramax Shaves Half Second Off 1/4 Mile Time

Hallman Chevrolet's "Truck Guy Joe" Fallon is outspoken for his love of trucks, especially diesel. The 3500HD Duramax owner delivers new vehicles to customers using his 2021 Silverado as the tow rig. A fan of racing, Joe recently hit the track to test his new Derringer and PedalMonster setup. At 14.1 seconds, he shaved almost half a second off a stock '21 Duramax! Not bad for a 12,100-pound 1-ton truck! However, Joe is quick to point out that as much fun as the Derringer is on the track, its 81 horsepower and 144 lb-ft addition really comes in handy when towing. Add the PedalMonster throttle controller and its a game-changer.
