If you had my money you wouldn't have to worry about a tune because you wouldn't have the blower in the first place.

As for mileage, no clue sorry.

I had gotten pretty decent mileage with my Casey tuned PWSC 26 mpg with alot of in boost driving.

Saying you'll get better mileage is more based on how your car is running now and obviously driving habits. If you're running fairly rich always I'd say you'll probably see a decent increase in mileage, how much though would vary on how lean. The joy of fuzzy numbers.

well look at it this way. a power adder is to actually increese volumetric eff. so if tuned right a boosted engine should in theroy make more power per air/fuel put in, but in practice you have to add more fuel to the more air........ so i dont know or care at this point cus im not boosted yet and i am jelious!!!! now i am gonna go pout!!!!!

I'm assuming that the current setup is a 'safe' tune, and is on the rich side. So, a better tune may be more efficient; i.e.: better mileage. The complicating factor is that I may tend to put my foot into it more, 'cause it has more ponies. On the other hand, if it makes more power with less fuel, I won't have to step on the accelerator as hard to get the same amount of thrust.
Oh yea, I almost forgot: No pouting on public forums!

i think the way it works is it makes a 2.0 act like 3.0. it ups the efficincy by stuffing morer air and fuel in a smaller hole.
