Re: '99 - '00 F250 7.3 Powerstroke
also forgot to tell you DO NOT put one of those chips in hypermax etc.---that engine has so much power it will drive right thru the trans and burn up the clutches especially if you are towing-- if you have a 3:73 rear keep it under 2000 rpm you get better mileage over 2000 rpm it kills the mileage
