Mornin' everyone, just purchased a 2013 Ram 2500 with the Cummins 6.7 to tow a toy hauler around for work. I've always liked more horsepower with everything I own. Soooooo, I bought a Bully dog GT. Seems to work well except my speedometer gauges do not work now! Both the digital and the one with the needle. Any help on fixing this would be greatly appreciated.
