Yeah, MPGs all depend on Cd, gearing, tire PSI, how good your tune is, and throttle input. In a stock height 2WD truck with a 5.3L, 4.10 gears, a good live tune, and keeping the truck around 60 mph, I can get just a touch over 21 MPGs.

I must admit I'm pretty skeptical about this. I've seen a lot of MPG threads and no one has ever come close to this. Then to say you did it without a tune makes me even more skeptical.
How did you calculate it?
I'm curious, as to mistakes are often make. Especially if you're converting KMPG to MPG
4.3,5 speed, 3.23 gears, A/C off, highway driving. It's also a stripper truck, the only weight adding option is the A/C. I calculate it as KM/L x 2.82
The 28 was a one time thing, perfect conditions driving a little better than reasonable, I average 26 and got as low as 19 at one point (cheap gas and a heavy foot)
Since I can't afford to knock on 11's I get a little amusement out of trying to make it as efficient as I can, once I can hit 30mpg the V6's life in the truck is over.

right back wind, and TRYING to get good mileage...its def possible (but really boring)
blown transmissions are about as useful as 97% of the guys on this forum
