I've gotten calculated 28mpg, and it should've been more like 30mpg cause I didn't drain the gas tank all the way down.
The trip OD hit 400, and typically fill-ups were about 13 gallons - you do the math.
Since I was doing such long distance driving, I wasn't going to take a chance and drain the gas tank that low - i.e. the fuel-low warning light never came on.
If I really wanted to push it, the car would've easily hit 30mpg.
This is driving between Sacramento, CA and Las Vegas, NV 100% freeway at speeds of 60mph to 80mph, just under the point where the secondaries kick in at 3,500RPM.
Back then it was stock ECU (well, reprogrammed G-Force unit) with full exhaust on a 1987 Turbo II.

Side note, I was able to hit 200 miles on a 10 gallon fill-up's.
I only fill up 10 gallons at a time, and it makes calculating mileage easy now.
Still tweaking the Haltech E8...
