18-19 highway
14.5 average, heavy foot. Frenchy, how the heck do you do that with the same power train as me? Or is that km?
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.
