I'm looking to run a good daily economy tune for my fx4. My current tunes have pretty bad mpg compared to stock. I'm getting 14mpg city feathering the crap out of it and max 16.5mpg highway. I use to get almost 600 miles out of my 36 gallon tank and now I get 400. That's being easy on the throttle for the full tank and using cruise control as much as I can. Just have a tune, AEM drop in filter and 170 Tstat.
Is there anything available that gives better fuel economy over stock???
