Truth is that they "usually" do not perform as closely the Ford Fagoners like myself and silver would have you believe, and that the gap in performance isn't nearly as wide as Government Motor Rednecks like Travis will preach. I do agree that mods are best left out of the debate for the Mach's sake. This particular argument is more than a decade old now...Murica.
Cummins vs Dmax, now that's an argument worth having, but not really Powerjoke > all.
