Looking to add some “bop she bop she bop” to your 2004 or later Dodge Cummins? The Xcelerator from Pacific Performance Engineering can add up to 145 hp and 290 lb-ft at the crank, according to the company. The programmer includes three power levels and enables users to make changes to the speedometer (for tire sizes ranging from 25 inches to 44-3/4 inches in 1/4-inch increments). It also retains the stock engine program so the truck can be reset to its original settings.
