On a trip from Norfolk, VA up to NH and back.. back when I had Wayne's tune I averaged 31mpg up, and 29mpg back down. I now have Tom's Tune but I've been driving a little more aggressive so I'm getting between 26 and 28mpg on the highway.
I recently picked up an 03 five door with a JRSC and from Kansas City to Summit Point WV for the SVTOA track event and afterwards down to Myrtle Beach SC it averaged ~32mpg with ~68 mph moving average speed.
Unfortunately, it turned only a couple of laps on track due to a bad fuel pump.
Ah, but Sebring is only a week away...
i get high 20's, 27-29, unless the temp drops below like 65 for any extended time, then i drop to like 24 or 25, thats all mixed driving (mine's a ZX3)
Just drove from Northern Virginia to Philadelphia and got 30.6. That was crawling for ~ 5 miles with an accident on I-95 and alo waiting to get out of the parking lot after the Phillies game. I was 75 +- up and back on I-95 (with the exception of the tie-ups).
