So everybody pretty much knows that for the ms3 the big 3 are intake, exhaust, and some kind of intercooler. Well my questions is specifically for the people with the big 3, pertaining to mpg. I just went throught my first full tank with my set up and i'm getting about 21 mpg...most of my driving is 75% highway. which makes me gringe at what it is in the city. with out the intercooler i was getting about 25 mpg...and the stupid fuel computer was way off it was telling me i was getting 25mpg on this tank. anyways i would like to know how everybody is fairing with the this date is a heavily modded ms3
