I don't want more power or speed. Just better mileage. Who has the best programer for milage increase on 06 ? Thanks

 

I believe both Edge and Quad make mileage boxes, mileage max and max mileage.

If it were me I would prob look at a smarty jr. It will add a little more power but the way its parameters are set a side effect is better mileage. I think you would find it a nice addition. 30hp would be a nice little bump.

Stock or not gauges are always recommended.

 

I have the Quad tow box on my 06, it did help the mileage towing and empty, have been using it since the truck was 2 months old, 76,000 so far, so good

 

fifty what are you getting on the highway without a tow ? I'm getting 20, but talked to a fella with an 06 w/smarty jr getting 25mpg. With what Obama has coming our way we'll need to squeeze every mile we can from a gallon.

 

what hp is that tow box. I've got an XZT from an 05, it's only a 65hp box
