The last four tanks my fuel economy has really been in the pooper. When I first had my tune done, the only changes I've made to my car is replace the vac lines, and regular service, fuel filter, oil, ect.
Last few fillups I've averaged 33mpg I used to hit 38 with the exact same drive, exact same driving styles.
I just got back from running boost and MAF logs. Not 100% sure what to make of them, but it seems like my MAF actual reading is decaying as RPM's go up. Don't know if that's normal. Log can be found here. Really would appreciate any input on it! I'll be going through the rest of the Fuel Eco 101 thread and check everything such as dragging brakes, and update as I go. Not sure if it's related, but on some occasions when I do a hard pull, sometimes there's no smoke, sometimes its a big ol fart of black haze. I do regularly do an Italian Tuneup as well.
