I've got the std.box on a '04.5 2500 4x4. I think you're looking at modest gains. (.5-1mpg more) Has your pops truck fully broken in? 25,000+ miles?
I haven't noticed anything earth shattering on mpg,even on low (30) setting.

Your Dads truck is going to get better mileage. It hasn't fully broken in yet.
I was getting 12-13 around 10,000. It got better 13-14.5 a little later. I went in & made a complaint about poor fuel mpg to dealer. They'll do whats called a flash for poor fuel mpg. It updates everything in computer. If I really monitor my driving closely, I can get 17-18 mpg (65 or under,highway driving)

As stated your dads truck will gain MPG after a few more miles. I have an 04.5 with a quad standard 100 HP box and I have noticed a difference all around. Mostly my interstate driving went from 16.7 avg to mid 18s! Thats almost 2 MPG. I do drive a 6spd so there may be a difference there. Keep an eye in the classifieds and you can pick this box up for $300 almost daily.
