Can "towing" and "milage" go together? LOL

My Ford gets 14.4 around town -- and it gets a flat 10 MPG when towing whether the trailer is empty or full. It's an automatic -- stock size tires -
not lifted - but I did do the Talon Suspension System on the rear. I am
running 4:10 gears.

Dieselplace.com is a great site for info.

My truck is 05" 3/4 ton crews cab LLY. Jody's tune picked me about 4-5 MPG, depending how I drive it though. Picked up a fair amount of power as well! On average gets around 15-16 around town and 22-23 on the HWY if I keep it in the sweet spot around 70-72 mph. As soon as push to 75-80 mileage goes in the toilet. Other than an air filter - that's the only thing I have done.

only in the fact if I wanted 10 mpg or less i would have just stayed with the bbc. I just ran first 100 miles in the truck and hand calc'd it at 14.3 bone stock. I would like 14-15 towing light loads and 18-20 empty would make me happy. I am sure a 38 foot enclosed behind it would be less

I'm running the Banks 6 Gun now. the truck came with it. If I had the choice I'd have the Edge.

Delco diesel in cow town has a nice shop behind their main shop set up specifically for tuning and aftermarket etc. Nice guys and they know their stuff.

The edge doesn't work well on the later (LLY,LBZ) dmax. I had one on my lbz and had all kinds of crazy problems. Edge finally admitted some trucks like it and some don't and refunded my money.

My cousin is using this on his lifted '07 GMC and has loved it! Along with the performance gains, he really loves that it's a programer and you dont have all the extra crap to mount on the dash. It took care of his larger tire size-speedo issue (speedo is spot on now) and the truck makes great power. He tows our dump trailer, that's a few thousand pounds empty, loaded down with building materials with ease. And on the weekends he tows his enclosed trailer w/ the drag boat, ect in it...that's a 12k # package. He's towed that from OR to AZ and back with ease.

I'm not saying it's the best...just saying he's happy with it !
