Conversation Between ComputerCowboy and Cactus Jack

I get about 10 overall now, I can do as much as 13 on the highway (not interstate)
As bad as six or seven in town.
When I got it the onboard computer read 11.2 overall.

bear in mind I removed the CAT and the stock muffler to get some of my economy back. I also added a cold air intake and I only run top tier fuel. I hope to get a little fuel economy back by regearing. I am planning to go to 5.13 gears and 38" tires which will give me an over all ratio of 4.30:1 which is supposed to be the best for the V10. I am also going to add a supercharger if I can find one.

Man your Excursion is really nice, how big was the loss in mileage from the stock suspension and tires to the 8 inch lift and bigger tires? I am looking at lifting mine, so I am wondering what I am going to be getting. Thanks in advance.
