I had a guy pick a race with me at the track in a new crew cab Viper Truck. I was driving my 8,000 plus pound 2005 crew cab dually 4x4 with a camper top. He spun and ran a 14.50.. I ran a 13.84.. I know this isn't exactly exciting, but it's hard to believe how slow a 50 grand "performance" truck can be. He said he had just spent 5 grand in lowering it, having an exhaust installed, intake, and new program. His best of the night was a 13.83. Kinda funny.. He must have gotten whacked bad if he paid 5 grand for those mods..
