So I just returned from a round trip from VA to AL and back and I tracked my MPG on my 2004 hemi. My truck is a mostly stock single cab 17" wheels, 4" cold air intake, bed cover, and a predator tuner. With a fresh oil change prior to the trip I filled up with 87 octane and switched to the MPG booster tune. During that tank I averaged 20.2 MPG. I filled up with 89 octane on the same tune and averaged 20.4 MPG. During this trip my average speed was 65ish.
With 1550 miles on the oil change I left on my return trip and switched to the 87 octane performance tune and filled up with 87. Running around 70 MPH I averaged 19.4 MPG. Filled up with 87 again and slowed down the speed to 60-65 and I averaged 20.7 MPG on the performance tune.
