I am running a 2002 dmax and love it. I consistently get 17 mpg with it. My question is what kind of mileage improvement can I expect with the Edge juice and Attitute system. Is it worth the $800+ dollars for just fuel improvement. It is a great improvement or just a marginal one. I have programmers on my GM gasers and they didn't seem to do much to improve my mileage. I was just wondering it the edge is a good improvement. I am not looking to do this for great power performance or power. Because the way I use it is just fine stock. But, I'm looking to improve the mileage. I know this topic has been probably beaten to death so I appologize for that. Thanks in advance.

you will see a small improvement, maybe 1-2 mpg at certain times. Is it worht the money? yes. the power increase and the mileage increase combined is definitely worth it. Just keep your foot out of it when you get the tuner otherwise it will be a mileage decrease.

It will help a very small amount if you keep your foot out of it. But that's hard to do when you feel the added power. Might look at the smaller version of Edge unless you want the gauges. I think it called Edge EZ. Good Luck

Dont pay $800 for it, shop around, I bought mine new in box from a dealer for less than $600.
