This is a question for you guys that own the 360. What is the average mpg that you get. I'm lucky when I get 13 mpg and I have flowmaster's, the drop in k&n, and a tonneau cover. I have saw no change in the mpg when I added these. If anything, it has gotten worse[:@].

 

Call yourself lucky, I have a 98 Ram SS/T reg cab shortbox 4x2. Hardlid k&n helix throttle body spacer and flomasters and I am lucky to get double digets[:@]

 

13, thats great MPG. I was getting 10. With the Superchip and K&N, I am up to 12. Winter sucks !!!!

 

Yea, I get worse mileage in the winter, I can't WAIT for spring and summer.

I am currently getting 10. 93 octane, K&N drop in filter, tailgate down. Winter really sucks.

 

Backdraft, check your manual. Mine says that for the 5.9, 87 octane is recommended and gas with more octane can hurt performance.

 

13??? that's awesome... I'd be so happy to get 13... but I've got a bad fuel pressure regulator... Any chance you can measure your fuel pressure and post it here?

Sorry guys... gotta ask.

 

I had no idea that milage was worse in the winter time. I had bought my 04 Hemi in Nov, so it's had bad milage the entire time I've owned it and learned to deal with it. Now I can't wait till it gets warm again!
On a side note, most of my driving is done in town, so my milage is usually around 13mpg. After a bit of highway miles this weekend, I'm up to 15!
