mine is at approximately 4 degrees advanced and i'm supercharged as well with a completely clean build. I am very surprised to see on highway trips with the truck totally loaded i'm, on occasion, seeing 12-13MPG with the supercharger. That's using actual gallons pumped and a GPS to track mileage. I would say on average i get 12mpg on the highway.
If you still have that K&N air filter in place, i would ditch it. Those things are really not worth it. You will get more oil and debris in your intake and on your MAF sensor.
