Default Diablo Tuner

Folks, what can I say, I installed the first tune out of my Diable Tuner and now the Hemi gets around 20 - 24mpg on the highway and that is with the MDS, "O F F", and 3:92 rear end gearing.............Now when towing, she drops to around 11-14 mpg..them horses are fat and sassy..LOL

That seems like a pretty large range. What was it prior to the tune?
Is that using the EVIC or actual calculation?

Hmm, that's interesting. Was the comparison during the same time of year?

I'm asking because I noticed a 2mpg difference between summer driving and winter driving. This is with no mods.

Anyone calculated city mileage? Im thinking of buying one just to save on gas, but my truck is city driving only.

There's allot of hills & mountains around here, I'm sure mileage would be better in other states.


Winter blends don't seem to effect the mileage with the tuner.
