Anybody out there tried or know of anyone who has used the hypertech e-con for their 5.9? I'm trying to get some better mpg without having to run premium fuel (and superchips flashpac fuel economy setting is only for the hemi's that I've found so far). I found this programmer on ebay (sorry i'm not pc savy enough to give you all the link) and they claim better mpg using only 87 octane fuel.

i have the max energy version of this programmer. The 87 tunes are exactly the same. I notice a bit more torque but milage and possibly a mile per gallon but im still running aroun 16mpg max. I know the guys at hypertech quite well and i do have a superchips flashpaq which made better power but cost more milage. The biggest difference between the hypertech and superchips was the hypertech could correct your speedo for different tire sizes and the superchips could not

ya i use to have the max energy and the only difference between the 2 are max energy comes with 3 tunes econ comes with just the 87 so u cant go up in power the econ is sapposed to be a downgrade from stock as the max energy is sapposed to be the upgrade over stock
