I've NEVER seen 20mg highway - maybe at 65mph cruising ... more like high 18s to 19. City about 12. I've put 30,000+ miles now on mine (BTW, they are no longer made) and have averaged 14.6 mpg combined over that time per computer. Of course, now around 680 hp (crank) though ;-)
I rounded up.
What did you do to boot it to 680? My neighbor has a Hennesy spec V sedan (I'm in Houston, so they're pretty close) that kicks out 650. I wan't to make him a little jealous. The best part is watching him try to drive it in the rain. Hilarity. Though he does have Pilot sport cups on it which aren't helping anything. Until he gets to the track.
Long tube headers, cat(s) delete, X-pipe, intake, 2.55 upper pulley, 8.x lower pulley, ported supercharger snout, dyno tune. Had CAM, but back to stock since so "lumpy". Mild suspension drop/wheel changes since so severely traction limited.
