well lets see..... w/ 3.23's i cruise about 2500 at like 82 i believe. a friends bird w/ stock 3.42's and M6 is going that same speed at around 2k. 500 less RPM's at the same speed and the fact that there is less parasitic loss is how its done ladies and gentlemen. Ohh and btw i get 330 out of my A4 on the Hwy and weve seen 415+ out of the M6 bird on road trips.

I had the same problem, it wasnt the plugs for me, it was my egr valve, I was getting 160 to a tank put a new valve in and now I am getting about 210 all city driving

I would get an SES light for the EGR valve but that was only at small random times. Usually it never came on but i was still always getting terrible mileage.
