When to EcoMod?

Yeah, my car already has real-time mileage and trip-average mileage already built into the display. After speaking with my tuner, I think I'm going to just follow up by getting a Tactrix cable, since he told me that he wouldn't be able to do a true economy tune. Some others I know have already gone down that path and provided the tables for doing so. If I have my own Tactrix cable, I believe that I will be able to modify the map accordingly.
