THIS....Worked at a Ford Store...Guy buys new 6.7 and have to put a HS tuner, delete the cat, download tunes, put ready lift in truck etc etc etc.. Don't make nothing doing it as a tech but hey they sold the truck!i worked at a place that had a truck with a plow. they tried to deny the claim. the boss told them you guys put the thing on. the warrenty claim was honored. the dealership I worked at pretty much approved everything. they didn't want to piss the people off. even when it was obvious it was the owners fault.they had a grand am come in with a supercharger. they told they guy he would have to pay them to remove it so it could be covered under warrenty.
