Thats what I've heard too, I heard that the normal techs and people at the dealerships can't really dig that deap, but if a Ford engineer comes in they will find it has been tuned no matter how much you try to hide it. Just ask around in your area and find a mod friendly dealer and you should be good. Also the new H&S tuners are different from the older ones. Due to EPA stuff from what I understand the new ones are hard to get with dpf off tuning. You have to prove that your rig is an off road or race rig only. I do know some sponsors on here still have the old ones in stock though.
