I have a 2007 Volvo Show Hauler motor coach that I use to pull a race trailer. The fuel economy is a horrible 5.6 mpg compared to friends of mine with Renegade motor coaches with the Mercedes engines or similar motor coaches with Detroit diesel motors. They get 7.5 to 8.5 mpg pulling similar trailers with the same weight or more than what I have.

Has anyone reflashed the ECU/ECM on their trucks to improve fuel economy? No one makes a hand held programmer that I am aware of for a Volvo....but I have found companies that will reflash the ECU if I send it to them with an increase of 20 - 25% more in fuel mileage.

Thanks for any offered help!
