After Grubb completed the installation, the truck was strapped down to the BDP Dynocom chassis dyno to see how the upgrades measured up. Chase Lunsford ran the truck through its paces on the dyno, checking each tune level on the CSP-5 switch. He found that the fuel system upgrades provided a more solid platform for making good, reliable power, as Dorn’s work truck showed increased horsepower and torque across the board.
In the lower tunes Dorn uses on a daily basis, the truck made 30 to 40 more horsepower than it did on the old pumps, while the more aggressive upper tunes saw around 10 more horsepower. On the torque side of the dyno graph, the truck made 35 to 70 more lb-ft of torque on the lower tunes with up to 50 more on the upper tunes. We recorded peaks of 478.7 hp and 902.7 lb-ft of torque—not bad for a work truck with over 200,000 miles on the clock. UDBG
