2013 Ram questions
if its a 5.7 4x4 its rated at 13/19 if its 2 wheel drive its rated at 14/20 use a calculator not that unit in the over head console for true milage,,, you can get a hand h held tuner diablo there are setting options, for performance and mileage,,,,diablo is untracable but you will need to put the factory tune back in if it goes for any type of warranty work or if they hook up to the OBD port,,
if its the 3.6 with 8 speed its rated at 25 mpg high way
