Thats with running excessively rich.

Actually, my '86 ran very lean on the Haltech (16.2:1 while cruising)

I could easily exceed 30 mpg with it.

I got about 28 or 29 running around town (driving it like I stole it).

Not too bad for 165 rwhp!

The '91 gets 20 city and 25 highway (best was 27.2 mpg).

So a couple weeks ago I took a trip up to Durham NC for a rally-x.
Before I left I filled up my tires to 35psi warm.
I got 28.0 MPG!!!
Then the next tank was 26.4 mpg.
I normally don't think of over inflating my tires, but now I do, lol.
