On the highway mine isnt that bad. Usualy somewhere around 30. I am one of the few that actualy drive the speedlimit so mine may not be too good to compare to. And my automatic, cruises at ~72mph at ~2900rpm's. I try to keep it below 3000 while on the highway cause Im shooting to make the tank last as long as possible. Sometimes I will get over 300 miles to a tank sometimes not. Around town my his utter ****. I sometimes wonder if I get over 20mph in town. You dont seem to be too far down on the mileage...what kinda rims you running? I noticed with Eric's 16"s I got hella better gas mileage. But I would possibly get rid of those NGK plugwires for some stock ones. That may net a couple MPG. But 27 isnt too bad I dont know many that get much higher.
