if I had to guess it would be pretty much the same for conservative driving. As long as you stay out of boost your ok. If your hammerin on it, gas stations are magnets to your car.

^I am looking for answers from turboed lancer drivers that can tell me from their experience how their mileage has suffered, improved or has not changed at all. Thanks for the guess but im looking for opinions from people who are turboed. Don't take this as me being a dick.

It's common knowledge that your fuel efficiency goes down with power. It's just how it works..
Simply put:
The more air that you have forced into your engine, the more fuel that you will need to prevent detonation.
anywhere from 20-26 mpg is in the normal range. I've personally talked to more than one Turbo'd lancer owner. They would concur with my approximation. I would not doubt a turbo'd lancer getting less than 20mpg. It all depends on how you drive.

Technically, turbos increase efficiency to the engine by adding pressurized air. The stock Ecu will continue to promote rich fuel condition so by tuning it and leaning it out you should get about the same efficiency as a non turboed lancer; 25-30mpg.
The higher octane fuel used in a turboed situation is used to prevent detonation, but as the amount of boost/pressurized air is added the fuel has to increase to compensate. Efficiency is measured buy the amount of fuel it takes to produce a given amount of power... so while the fuel consumption might go up, efficiency is greatly increased.
I'm only saying this because even if you lose 5mpg, your car is technically more efficient with a turbo, but defiantly not as efficient in fuel consumption.
I'm still interested in what people have to say as far as what kind MPG they are getting.

I guess one of my questions would be how do you stay off the boost on a car that boosts from 2,500-4,000 rpms? I mean if I'm driving as I drive now I'd almost always be under boost.... and at highway speeds in 5th gear doing 60-70mph I'd always be running boost.
So if I'm somehow burning more gas under boost conditions I'd almost always be gettng crappy MPG? right? Perhaps someone can explain this one to me.

Even when you're "in boost" you are not really boosting, and I'll clarify.
I used to hit boost at about 2200 RPMs and full boost at 3500 or so. However, when cruising, you arent really boosting per se. You only boost boost on throttle (i.e. when accelerating). On constant light throttle, the boost gauge would be at 0 psi and even down in vacuum sometimes, or reading slight boost. So wastegated at 12, limited at 20+, I was never at that boost level while cruising. So picture this, you're at 60 but at 0 psi cruising at steady throttle. You need to pass someone so you step on the gas and the cars builds boost and you hit 6 pis goign up to 70 to pass, then back to 0 when you are back at cruise.
Does this make sense?
