i had a problem with my emissions junk and was getting about 4mpg with a 5-6:1 a/f ratio. it was rediculous. i fixed it and was getting about 22-24mpg. this was on 9psi or so with an intake, exhaust and a few other little things.

tim how do you know yours runs 5-6:1? most of the wideband or any sort of thing can masure the rich.. some of them goes to 9 at the lowest. and it should read rich or some sort.

Hmmmm, I was kind of hoping for some higher numbers because it is such a small engine, but I guess that's the price we pay for an awesome turbocharged engine.

I NEVER saw below 21mpg. Generally got mid 20's (all intown driving) but I'm sure that if it was strictly highway driving, I could get high 20's. If you stay out of boost, the gas mileage really shouldn't be too bad. And if you're cool like me, you'll get a standalone and you can tune it to get good gas mileage for everyday, and then tune it to kick *** when you need it to! Hehehe
