Updated with some more numbers - will fill up again tomorrow but as we are on I-40 with the AC on all the time and 65-70mph to keep up with traffic, I am expecting us to be around 7mpg
Interesting that if I take a hill at 60mph (2200rpm) then I slow down to 50mph at the top but if I take it at 65mph then I can maintain that speed all the way to the top - definitely a 'power band' with the Banks
Sorry Gjac, I purchased the rig with the Banks installed so no experience without it - my previous older rig was a 454 Carb so apples and oranges.
Maybe someone else has mileage info on a 22k# rig without Banks?
