Difference between pretty much stock and tuned are pretty much stock would only consist of BASIC bolt ons, like an intake, ignition and exhaust, tuned would be more, like motor work, turbo etc. You know how it works. VOTE.

Ive got a custom WAI I modified from my 2004 sunfire GT and thats it. My last 2 tanks were 28.02 and 27.88mpg EDIT: im auto too

EDIT:
Im 90% city, so I think im doing okay. It was a little worse before my tune up

 

Define tuned a little more, I don't have any internals yet but when my head blew they did a nice polish job for me.

 

Anything more than the bolt ons I listed. Headwork would count

 

im confused as to what catagory i would be under[&:]

 

i still get around 37 or so MPG on the highway...and thats after 240,000 miles on it... and its a 5-spd...purdy good

 

My '99 R/T is bone stock and averages mid 30's. On the return trip from the Nats to NJ, we got 42 mpg with the cruise at 70 and the air on.
Not too shabby...

 

Well anything more than a simple intake and exhaust would be considered "tuned" and would have more of an effect on the engine, like a turbo or soemthing. Headwork counts too because, well its headwork

 

when im not driving the car for work i usually get about 32
if im driving the car for work then i usually get about 19-25

 

your race car? itll still get 32?? stupid automatic. How much is it hurting my mileage? (Though im above par for mileage with my carb'd accord, so its not really a big deal)

 

my race car???
auto only drops down a few miles....not much
