gettin a custom tune is the easiest way to get more hp out of a vortec. my truck gets 17 to 18 mpg hwy and 13ish back roads. specs are 97 k 1500 1 ton sas 4.56 gears 315-70-17 mt. vortec 305, headers, 3" single exhaust, no cat. built 4l60e with towing converter. like 1300 stall. i believe that helps mpg alot. 4.56 gears are nice on the road but too slow in low range I top out at like 35-40 mph. not very fun for racing at the dunes. just my .02
