Damn am I the only one in the 11's? I usually get 11.5 -11.8 in the city depending on driving habits. I don't drive enough highway to get a good accurate measurement.

If I use the remote start for too long to often it dips into the high 10's low 11's.

Thats with the 22's everything else bone stock!

New plugs, wires & o2's went in over the summer.... Might have to look into a tune and possibly CAI!

How aggressive is your setup? I wouldn't mind 10.5 If I had a blower lol

My combo in my VMAX 6.0, LPP lontubes, Offroad Ypipe, MIT Airaid Intake, Chipped up, 305/50/20s a 32" tire, gets 320 miles a full tank. Thats with 3.73s, and Im about to switch to 4.88s in a few weeks. IMO its about how its tuned and setup, and how efficient your combo is.

SC88: I did the quest for mileage last summer. O2 sensors found 1 or 2 mpg. Plugs, wires, and CAI cost me 1 or 2.

You guys with the 35s and 6in lifts seem to get decent mileage!

I average 13.5 to 14.5. 17 on the highway, down hill wind at my back.
