Re: Official post your mpg's.

Here's an update from my Post No. 17, based on my last trip. Best mpg (see mods. below) was 24.41 mpg, and the average for the whole 2446 mile trip was 22.08 mpg. Here's the thread I did on that trip, FWIW: One More Hemi Fuel Economy Thread

I run the SC 91 tune with my custom shift schedules. The fuel octane I run normally depends on the altitude(s) I'll be driving at and the ambient temperatures. Note that my best economy on this trip was with 85 octane at altitudes around 5000 ft. Most of the time in the dead of winter (coldest) I'll run all 87, in the spring and fall I'll usually alternate 87-91 (depending on the ambient temps.) and in the heat of the summer, I'll run all 91. Around home, all fuels are non-ethanol. I can easily tell if I am not running a high enough octane by monitoring my knock retard with the onboard DashHawk.

Re: Official post your mpg's.

My girl is best friends with the skinny pedal, and it's currently her dd, so right now the hemi is getting almost 10 mpg. Im hoping to get some info on the super chips tuner and what this trans app is all about, maybe I can get her to recycle the dinosaurs a little slower if I do.
