I switched to a 275/70/18 Cooper ST Maxx (AT/MT "hybrid") and a 2" Zone leveling kit and dropped around 1 mpg.

Yes Sir, I took it to the dealership and they "adjusted" for the tire size. I was showing 70mph but actually going 76mph. Now, since they did that, when I'm showing 70 I'm actually going 72. So it did something...

I'd be STOKED if I had lost just a mpg avg...

I didn't get angry; re-read my post and don't see where/how you took that as anger...just stating the facts.

I took it as at least "snippy". Additionally, I understood what Barrett was trying to say with his post.

Inflections and tones get lost through the typed word. It's OK though. I get "misunderstood" all the time!

Now, you fellers have a frosty, cold

and make up right this minute!

I went with a rancho quicklift and 35s but thanks to my Edge CS Eco tune I am actually getting 1-2 mpg better than stock

If you're using what the Edge is telling you for MPG, I wouldn't. The Edge (all configurations including Gryphon from PHP) is notorious for showing incorrect MPG calculations.

The good, old-fashioned manual method of checking MPG is the most reliable way, IMHO. It's hard to imagine that a 1-2 MPG GAIN is possible with heavy-*** 35s AND a lift.

I am using the fuel economy display on the trucks instrument cluster. Other than the parts the only thing that has changed is I moved a mile and a half farther away from work (50 mph speed zone). I really dont think that would affect my mileage especially considering I only drive the truck 2-3 times to work during the week because of company vehicles.
