Default Great MPG

I have a 2009 with 5k miles. I also have a vararam over the radiator cold air intake and the Superchips Cortex tuner. With the OTR I averaged 22.8 MPG on I95 from Charlston, SC in 90+ degree weather. With the 87 octane tune, I averaged 25 MPG from Wilmington, NC. Both were at an average of 71 MPH on hot days with the AC. Once I combined the OTH & Cortex tuning for 87 octane, I averaged 29.4 MPG at 71MPH on a 170 mile trip. My average around town is 19 - 21 MPG which is GREAT!!
Maybe headders in the future?
