I drive it like I stole it! I have a 2005 QC 1500 with 59,000 miles. I always have my foot into the pedal. Even with 37" tires, I still don't like when anyone beats me off the line! I get an average of 13.3. And that is good considering the tires, lift and just the way I drive!

 

im with nitto, i drive it hard, with 35" all terrains, 63000miles. I think i got a 3.55 rear, and with 4x4 and quad cab at around 65 at about 1400 rpm on a dead flat road i can see as good as 21mpg! I even reprogrammed for tire size with my superchips tuner

 

of course the 4x4 isn't on /\ /\ /\

 

xfeejayx, after your post, I thought that I'd try opening it up every now and then.
HankL, after your post, I thought that I'd test that out.
But after seeing your post dodgenitto, I think I'm gonna try the opening it up for a while. If it doesn't work, then I can be easier on it.

Btw, what octane should you run in an '03 Ram with a 5.7?

 

i got mine tuned so im running 93, with stock computer u should be fine with 87
