Which custom tunes for me

[Alcohol5LT]

I'm looking at finally ordering the custom tunes for my truck. I've got the gryphon with my 2005 F150. I've been wanting to order an 87 performance tune, but am wondering if I should go ahead and order a custom 87 towing tune too. What I'm trying to get is the best mileage out of my truck. I usually run the 87 canned tune.

I have the 5.4L 3v with a K&N FIPK, Flowmaster Catback, Efans, 35'' tires, and will probably get some underdrive pulleys to put on before my tunes arrive. Any help you guys might have would be appreciated.
