I would just watch the egt, and if it trends higher with the load, stop and grab a coke and switch to the tow tune. Most tow tunes run close to stock injector timing, which keeps the egt's low, and helps at the bottom end. I tow my 16ft. Carolina Skiff on Looney some times when I forget, and it stays below 1000f. Any heavier than that, I always run the tow tune.
FORDMUGG- Try the Street Looney. It spools the turbo faster, and slightly lessens the cloud when passing on the freeway. That's what I run daily. Their straight economy will supprise you, too. It gets up and goes. Alot of "out of the hole" power that's good for traffic situations. The Looney will give you the best MPG though.
