Daily driven Ls powered s-10's inside
 

I was just fixing to get the exhaust on mine and hit the road in the next couple of days. for those of you that have mild mods no big cams or anything and an average of 3:42 gears what kind of mileage are you getting out of them as long as you behave. Mine has a lq4 6.0 with an ls6 cam and springs and headers. The dyno tune is coming soon right now I just have the vats deleted so I can move it around.

Just took a 400 mile round trip (all freeway) 70-75 mph and got just under 25 mpg.
LS6, 3.42 rear, and T56 gearbox. 1750 rpm at 75 mph.
