12mpg on E85 mixed driving ie. spirited boosting, little highway and a lot of city driving. I drove it to MO (700 mile round trip) last month and I did about 320 miles to the tank. That's about 19mpg....pretty shitty IMO. This was on pump gas though with an untouched tune. Speeds averaged 75-85mph.
In my old Talon I got much better gas mileage but I ran that car in forced open loop all the time and my highway tune (15-16AFR) was dramatically leaned out for fuel economy.
