Just bought an 06 1500 4x4 mega cab with the 5.7 and 325/65/18s. I have yet to see over 10mpg out of this pig yet I hear of so many getting in the teens... I know the tires and 2.5"/1.5" aren't helping but what should I be looking at?
(Yes I know HEMIs get horrible FE lol)
Pretty much what I was thinking. I was like man I know it's a hemi but jeeeeze. Superchips is my next step. Any ideas where to pony one up for less than $350!!!
Seems like from what I've heard superchips or diablo is the best route for the hemi...?
And I was talking more along the lines of a used one in the $200 range
if you do get something to recalibrate your tires (which I bet will help your MPG read out) make sure you physically measure your tire height, don't go by what it's supposed to be by the info on the sidewall
You may also see better mileage If you hand calculate your MPG
I know that my Ram EVIC MPG average is off, as is my odometer reading by close to 3 miles per 100 miles
I have an 08 QC 4X4 and over the last year I average 12. even. That is using the mileage from the odometer and using an app on my phone. Highest I got was 14.58 and lowest is 10.71. I just installed a Volant CAI and a Diablo inTune and just filled up so interested to see in this next tank what it is like.
Update:
Cleaned out the throttle body, new plugs, cold air, and superchips 91 tune with 91 no ethanol. Im about 15-16 on hwy at 62-65mph and about 11mpg in town. Dual Exhaust will be next and hopefully help some more.
