( http://www.TFLcar.com )  Run what you Brung is TFLcar new feature that pits our viewers vehicles against the altitude and the clock. In this first episode we test a 2008 Ford F-250 Diesel pickup from 0-60 @ one mile above sea level to see just how fast a 4X4 heavy duty Diesel pickup will go with the right modification. Do you think that it is possible for a heavy duty Ford to break 5 seconds from 0-60 MPH? That seems like a tall order especial since there's less air pressure at a mile above sea level which robs engines of horsepower. To find out the answer...just watch TFLcar's Run What You Brung.
