Was wondering, for kicks, what kind of gas mileage everyone has been getting with the MS3 cam with 3.42's? I'll be the first, i get in between 17.6 and 19 MPG with an M6 with stock gears (3.42's). With 65% highway and using 6th gear with the tsp 5.3 heads.

i'm not worried bout the mileage, just wondering about the tune, i heard that it shouldn't be that bad, and if it is, its in the "tune". When the car was stock, i got 21-25 all around..now 17-19...for the power differance, so worth it!
