great mileage

Keeping it under 2000 RPMS, I've been getting 19 in mine. Now normal driving, I get 16.

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.

if I do mainly highway cruising I can get 21-22 mpg, but if its all city driving then only about 14-17. I have a heavy foot too, so I cant complain

You would be better off getting a port and polish job on your stock throttle body by someone who's reputable, better results per $. ;)(would be around the price of a tb spacer)

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)

Ah didn't realize it was a V6. That explains a few things.

You know this is predominantly a performance site right:LOL:?

Just kidding with you man.

Haha yeah I'm well aware, but there is more to performance then going fast in a straight line.

ya and i love throwing this in the face of my friends, one has a dodge, gets 16 or 17 at best on highway, a new tundra, gets 16 on a really good day, a titan, which is about 17. i all told them and they are like are u serious dude, the dodge guy was at the chevy dealer that evening trying to negotiate a price
