I don't trust the display. I'll reset the MPG counter when I fill, and my trip odometer. I'll run through my entire tank. My display will read at least 1 or 2 miles per gallon lower than my hand calculations of miles driven divided by gallons used.

But I generally get 25-27mpg. I drive about 40% highway, 60% city, which hurts it, but if I'm taking a long trip, it flies past the 30mpg mark.

Edit: Forgot to mention, Unitronics chipped 180Q, no other mods, generally a semi-conservative driver, but I have some fun every now and then.

 

I average around 24mpg. That's probably 80% highway, but I drive fastabout 50% of the time. Even if I don't push it though I can only average about 26mpg. I think I might try and air the tires up a little higher.

 

I only fill up once a month or so. The longest I've gone is 6 weeks without a fill up.

Of course, I work away from my car and I have a company rig to drive around. So I get to visit my TT about once every two or three weeks.

 

Do you do much street driving with it? I thought your TT was track only, or at least only street driving to the track.

 

Yes, it is still a street car. The ride is a bit rough, but it is still a blast on the winding mountain roads around here. It's just mostly a track queen now, since that is about all the extended driving I do with it. But I still like to take it out and give it a little exercise now and then.

 

I average about 23-25 and I drive pretty agressively (mostly street driving to and from work). I averaged 30.7 on a recent trip with 2 people and 500lbs of supplies to Helen GA (=Mountains).

180Q with Unitronic, water meth, TIP, and gutted intake.

 

My average is like 17mpg city and highway maybe like 18 mpgtops on the highway, its really bad. And i just changed my o2s[:@]..any suggestions??

 

lighten up your right foot.... ; )

Dirty air filter, worn/poorly gapped sparkplugs, clogged injectors, soft tires, driving in boost a lot, bad gas...

Could be any number of things.

 

I'm not in boost all the time, tires are always perfect as far as inflation goes, plugs are always clean and gapped. I average 27-28 and on an extended highway run can get about 32-33. This is with a Chip and full 3" exhaust.
