Just wondering what everyone else gets. I only get like 13mpg max, and thats driving it pretty easy the whole tank. It's on 13psi though...

i didnt notice a difference unless i boosted. If you dont boost and you have poor gas mileage, you O2 sensor is gone or your tune is bad.

hmmmm, O2 is good, not sure about the tune, it was done before i bought it... I know it runs super rich due to unburnt fuel stains on the back and a big cloud when i am full throttle. My a/f gauge seems to read about normal though

Are you sure you have 13psi on the supercharger?! If so, what are your mods?

I'm getting 18mpg on 9psi... but I do tend to hit the throttle more and more, which makes it bad.

The way I'm tuned at highway speeds I should get 25mpg at least (I hope). But for now this is 2/3 city driving 1/3 highway. (a 25-30 min. commute each way).
