OK I don't want to start a Riot or anything, but I am looking for a computer monitor(box) for my 99 Dodge 2500 24V. Currently I am getting 15MPG a heck of a lot less than what I expected. That is since I put a 4" exhaust turbo back on the truck last week. Well my point is I want to know if anyone has researched to see what Monitor (box) is the best on fuel mileage? I am interested in the Edge Juice w/ monitor, since it has all the gauge accesories with it and I do like to see what my temp/pressures are going to be. Has anyone bought the Edge Mileage Max yet? IF so how much did it improve for you. I would like to see the mgp figured by hand since I have heard that the digital displays are not all that accurate. Well Guys and maybe gals let me know what you think about the boxes, I am shopping for one or anything to help out my MPG. Other mods this weekend, valve body and bigger air intake! With that my truck seems like it gained 50-75hp. Thanks for any input!
