which downloader gets the best gas milage?

I haven't seen much of a fuel mileage increase using the Bully Dog, Smarty, or Superchips. I'm kinda of skeptical that you are going to see that 3-4 MPG increase...

Smarty set on SW#0 will net you the best fuel economy.

My smarty jr on economy gets atleast a solid 1mpg improvement , 2mpg when I drove for 150 miles at 60mph unloaded.

On the performance setting, my mileage stayed the same as stock, not bad for an extra 100hp.

I didn't see much of a change with the SMARTY. Economy didn't go up but it didn't go down either. And it's set to 100hp.
Still getting around 21mpg highway (70mph) and 17mpg city.

My fuel economy did go down with the Edge EZ, and that was only 50hp.

I saw very little bit better with edge ez, nothing with edge juice, superchips, or the quad pressure box. Bully dog made it worse cruising, but better pulling my trailer.

Smarty on #5, I gained about 50 miles per tank, best yet. Every truck is different thou. Can't go wrong with smarty, lots better than I thought it would be.

I get my best mileage out of SW7 with the Smarty
