I'd say 20 miles / gallon....not sure....it all depends on how the engine is maintained.

I get about 21-23 highway with a base 87 with all the options. I really don't know city too well, since I never really get city miles.

Best I ever got on my TII was 26 mpg.......city driving is probably around 15. Rtek 1.5, Racing Beat Turbo Back and about 10 psi. I didn't buy this car to save gas. ;-)

My GTUs gets around at least 22 mpg highway believe it or not. It used to be much worse until I did a full tune up, fluid change (w/ water wetter), and replaced the O2 sensor all of which helped I'm sure...

25 mpg on the highway. I wonder what SonicRat's setup was to get 31 on the highway? Aftermarket ECU???

Nope.

'89 GTUs, cone filter with a box, 2.5" off my manifold to a resinator, then 3" back to a y-pipe, and 2.5" off the Y to two ebay mufflers. Had a complete tune-up, also had a vac leak. Running at around 75-80mph on the highway between Ohio/Pennsylvania, yes my aux ports were open since that's around 3750-4000rpm on that car. EGT's were around 730C, just barely sitting in closed-loop.

um.. I just got 11 MPG on my first tank of gas after my Megasquirt was put in.. Of course, I only really used about half a tank, and this only included about 60 miles of actual "driving", a lot of idling and 11 autocross runs... So I'm happy with it

With city driving and a few spirited runs down back roads I get ~18 mpg. Thats with a N/A that has exhaust and a basically hollow cat.

Hey Rat, you in Houston yet?

My last fillup (yesterday) was 28.18 mpg, and I bet if I could keep my foot out of it I could hit 30 easily...

How the heck are you in closed loop at 3750 rpms? I thought closed loop kicked out at 3500?

That's strange, I can usually be within closed-loop up to about 4K. Yeah I'm in Houston.
