Thanks for the tips. So how reliable is the computer MPG and instant MPG on these trucks when stock? I know adding a tuner will screw them up but no plans on doing that for now.
They're not called Lie-O-Meters for nothing:).....Best way to figure out mpg is fill to same place each time, (when pump cuts off), then hand calc MPG....I got better mpg with the 2012 than the 2010 and I get better mpg now, then with the 12', but it's because of the DEF. also have the Aisin in the 13'...but 68RFE with DEF should also get better mpg....from all I've read, when towing, there really ISN'T that much difference when towing heavy between 3:73 and 4:10...3:42 works a little harder, MPG isn't as good.
