14.5 average, heavy foot. Frenchy, how the heck do you do that with the same power train as me? Or is that km?

[Frenchy]

Nope thats 24 mpg. Uhm 5 speed and 3.23s. A lean tune with lots of timing. When I highway drive I tuck up behind anything bigger. And I've spent a lot of time teaching myself to drive economically. I've put quite a few tanks through it and got no better than 17 and I've seen as high as 26.5. It's all in the driving habits tune and maintenance. It takes literally almost no throttle for my truck to maintain 60 mph. Anything above that I'm cooked though.

My Denali gets 13.5 with mostly city driving. That's with the wife driving it primarily, too, but she's almost as heavy footed as I am.

Lol no at the time it was on thetrailer it wouldn't idle. The 35 is a guess. I drove about 200 miles on 6 gallons so I'm not sure exactly what it gets since I have no speedo or gas gauge
