Default MPG for 07 1500 5.7L Hemi

I've had this truck for a little over a year now, and the best I've ever got was 15.946 mpg, checked on paper not the EVIC. The lowest I've ever got was 12.594 mpg, but that was keeping my foot in it pretty heavy lol.

I've got 285/65/18 Nitto Terra Grapplers, a 2.5" Rough Country Leveling Kit, Bully Dog Programmer on Regular Octane setting, AEM Cold Air Intake, and an Airaid Throttle Body Spacer.

If I drive it easy, it'll get 15-16 mpg, which is pretty good for an 07 Hemi, I think. What is everyone else getting with their 07 Hemis?

Is your speedo calibrated for the tire size you're running?

Mine got 16 when I had my magnaflow on it, and a fresh oil change with RP. Right now I need to change fluids and have stock exhaust and I am getting closer to the 11 mark. I think that is about as good as these early 3rd gen hemis get.

Ive got true dual magnaflows and fresh oil CAI and tuner are both next in line on the mod list so im really hoping combined they help a lot. Im going to calculate this tank by hand to see how accurate my comp is. I also run 87 oct. gas and not mid or premium, but I cant believe thats going to make up more than 1mpg.
