What kind of mileage does your Mega Cab Hemi get and with what modifications? Lets figure out the best combinations for savin at the pump!!

 

Below is what I am averaging- the last 11.46mpg is with the True Flow XDI installed after 45 miles - but I had my foot in it alot but I did have about 100-120 miles hwy. The tank I am on now I am driving easy like I normally doand I am at 50% city/hwy and I am at 12 mpg avg right now after 70 miles. I will beregearing to4.56's which will help to get this bohemeth up and moving and will be a big help to releive the strain on the drivetrain. Should help with city and hwy mileage quite a bit. Also going to add headers, tuner and exhaust to help a bit. I will be going to Alabama on the 26th, I am hoping to avg. 15 or so - it is a relatively flat drive so hopefully I can beat my 14.7 best.

[Edit] [ Delete] * To accurately calculate fuel economy (MPG), you must have a minimum of 2 fill-ups in a row where you completely fill the tank.

 

I average between 13 and 14 mpg with mixed driving. Straight highway I get near 18 with the cruise set at 75 and near 19 when 65 or less. See mods in sig... BTW, I drive my truck, I do not baby her at all. I let the Hemi SCREAM.....

 

L and R - what gears - tires and are you 4x4?

 

Gears unknown
Tires are stock 17 rims with the stock mich tires.
4X4 is a no.

 

I would imagine that you have 3.73 gearing if it a 2wd.
