LOL sorry posted in the wrong post. Seems like the 6.2 gets better MPG than the 6.0. MY truck just has the diablo predator tuner.... I think I need to get a real tune!

99 has LQ9 6.0. I wish it was the 6.2!

and yea the 6.2's when tuned do really well if you keep your foot out of it

Vegas Panton

2010 ECSB 4X4 6.2 3.42, stock sized tires: 18 to 19 mpg all day long at 75 mph.

After ripping the plastic air dam and a fog light off on a moderate to easy 4X4trail on Colorado I raised the truck up a moderate 4 inches.
MPG results: 15 - 16 mpg at 75 mph. However, so far I have kept the air dam intact.

As expected city driving was the same before and after the lift at 14 mpg.

Conclusion: The air dams really work well at keeping the air from underneath the truck and decreasing the drag.

Taking my 6.2l on the highway for a 2 hour drive up north. Bb tune and headers, hoping I get 20mpg at 75mph. I'll report back later. Ohh and I'm running 92 octane.

Did the tune turn out to be all that you were hoping for? I don't remember seeing an update.
