With the mods in my sig, I am getting 18-18.5 city driving in Colorado Springs which is at 6000' I run 285's for tires. Before the chip, I was getting 20 highway driving through the mountains. That's at 55-60 mph. With the chip I haven't checked mileage in the mountains but I will this weekend to and from my elk hunting trip.
