Its probably just the kind of driving your doing. Those are just a bit lower than my city average. I usually get about 13 because of stop and go traffic. Do you have any other mods like heavier tires? Also what is your stock gear ratio? You could try going into the custom options menu and lower the 3rd and 4th gear shifts and the 4th gear torque converter lock point (both lock and unlock). That might give you a small improvement. When I did that I got an extra mpg or two in the city.

Here's a list of OEM rear axle codes. You can find the code for your truck on your driver's door sticker.

19 = 3.55 open
H9 = 3.55 LSD
26 = 3.73 open
B6 = 3.73 LSD
27 = 3.31 open
18 = 3.08 open
25 = 4.10 open
B5 = 4.10 LSD

Yeah, that gear does great on the highway but not so great in the city. How many highway miles are you going through to get that average?

Like Jack mentioned earlier, the gryphon average isn't always correct. Just keep getting your average like you would without the fancy technology. Pencil and paper. That is always more accurate unless your tires are the wrong size from stock. That will throw it off too.

i have 35's on right now, and the mpg went up to 14.1 today but now at 13.7, i think it might be the way i drive i guess?

***Longshot270*** · #8 Tue, March 9th, 2010, 07:14 PM

The gryphon average will change quite a bit until you have at least 30-45 minutes of driving. Is the 13-14 city, highway or a mix?

I dont think you are doing to bad with having 35's on with 3:55's

Heck I have stock tires 3:73's 5.4L and I average between 13.8 and 14.7 with mix driving.

You need to fill out the rest of your user cp!
Just your name is there.

That's about where my mpg's are right now with the winter blend crap gas.
