Considering I have an aerodynamic disadvantage all ready (my utility bed), I've some how managed to start getting 18-19 mpg. I've read a lot of threads and sales pitches about programers that mostly boast power and hints of improved mpg. Any particular ones stand out to you in the mpg department? No looking for much in power gains as this is my work truck. And in Alaska, there is no such thing as a short commute to the job site. So, more mpg is desirable.
Anything to watch out for on "used" programmers?

 

...............I use the Edge EZ.........I used to get 800 kilometers to a tank, now I get 1000.................kim........

 

20%, not bad. Do you have an auto or manual? Any other mods?

 

Just ordered the Hypertech Max Energy Power 52500. Error - Hypertech Cheap enough to not worry about it not performing. It reprograms your stock computer so there are no add ons or wiring hacks. I'll see how it goes.
