this last tank was 23mpg 218.8 miles and 9.493 gallons, consisted of 1/3 my 3 mile commute to work stop and go, 1/3 weeked cruising, and 1/3 tuning and boosting the **** out it. overall i'm pretty happy with that considering stock was rated 21city 27 highway on my 93.
But i'm wondering if i can do better. is anyone beating that without highway driving? if so what are you're afr's tuned at idle, normal driving, and cruise? or any other tips to improve any in ms?

Boy, I wish I could average 23 mpg! ![big grin](https://www.miataturbo.net/images/smilies/biggrin.gif)
On the highway with the top up, I get just about 30 MPG. Despite being small and lightweight, the Miata is not very aerodynamically efficient.
In town, 19-20 is more typical. Of course, I'm not terribly gentle on the throttle.

man ive been babying my car around lately ... hardly even hit boost anymore with gas prices. Anyway ive tried to tune pretty much anything under 70kpa to around 16:1ish and have aggressive EGO correction up to that point to keep it running lean (15% max change, 32cycles, stepsize 1, 1500rpm)
Anyway, ive gotten like 20mpg in the past but recently went more lean with my fueling and i think its going to get a few points higher this time.

Since I've switched to COP's and bumped up to the "hybrid" spark map, the lowest tank I've had is 24mpg... and that included a lot of boosted tune runs. I'm pretty sure on the freeway at 70mph w/about 15-18vaccum, I get about 30mpg. But I also see 14psi at every stoplight, every onramp, and every Honda.

It's fairly irrelevant however, as we tend to remove all the bits that differentiate the cars when we go MS.

I suspect that the difference has to do with our fuel having a lower energy density.

I got 25 last tank, due to the top being down and nearly all city driving. With the soft top up, I'll get nearly 30 and over 30 with the hard top. This includes WOT from 1st to 4th as often as possible, as well as plenty of pulls from 4 to 6-6.5k in 5th--Just so I can hear it go "PSHHHHEWWW".
