Hi. How do you know what speed your truck is governed at? I was on a deserted straight country road one summer day, just me and the cows, and thought I would let the 315 Horses under the hood run. I was well over 90, and let off the gas to coast back to the speed limit (50). Far off in the distance I see this dot of a car coming toward me. As it approached I saw the black and tan of Md state trooper and as he passed he hit his brakes and turned around. I pulled over before he even had his lights on. He wrote me a warning for 66 in a 50. Glad he didn't pick me up at 90+.
