Should run better than that. Mine run mid 14s all day long with those same mods. Went to a 3200vig and run 13.9s. But your truck has a few miles on it...

Yeah mine and my buddies ext cabs were identical other than he had shorties and i had long tubes and they both were neck and neck around the mid 14 to 14.2 and that was the best pass..

Oh and lglowes truck is a 2wd. I think someone asked..
