odd that i did perform a search with mpg and turbo, yet must've overlooked that one... my bad!
tnx a lot, though
ooook...
i've read the topic, (trully interesting, no questions about that) but i was looking for something more specific then a generalisation of FI effects on mpg.
namely, a before-after mpg? i know driving styles have a big role in mpg, and that is precisely why i would have liked a before-after mpg of the same car/driver.
as well, provided some of us have other turbos then the greddy one, a comparison between their general effect on mpg/output at certain boost lvls, mayhaps....
still searching, no need to shoot me down yet :P
tnx

Interesting, so if you go FI, you get less MPG?
I used to own Audi S4 Twin-Turbo, Stock boost was around 9 PSI then when I chipped it, I was boosting around 18 PSI.
I actually got better MPG(around 24-26) with the chip when I drove normally, then when I go crazy, I got about (9 to 15 MPG)
Oh, in stock form I got about 19-21

At cruise my mpg were better with the turbo. The furthest I went was about 290miles before I had to refuel, vs about 260 NA. That is mostly due to tuning though. I drive like a grandma with the turbo because I didn't want to boost much during city driving, and I'd still get about 15-16mpg, but with NA I get about 19mpg with slightly more aggressive driving.
