the only thing i can think of in your case being that you switch back and forth between different tire sizes, is a superchips tuner or something that you can consistently input and program. it'll cost you 350 bucks, but think of it this way, it costs 100 bucks to get ford to adjust it for you. if you will be switching back and forth between tires sizes it might be a good investment.
