Tunes depend on the amount of weight. I tow a 13,000 5th wheel using Matt's unlimited tow and elite's as well. You don't get any extra horsepower with these tunes, they do turn the egr valve off as I don't have my egr system deleted. Sometimes I'll run it stock, but I do notice my egt's a little higher.
Now, if your towing up to 8,000lbs Matt's tow tune works great and I get better fuel mileage as well (not much just a little).
Your best bet is to work with the person who will write the tunes to get it dialed in at the best setting.
