See my sig for TV and TT specifics. We get about 10 mpg in the hills and 11.5 mpg on the flat roads towing in tow haul at 65 mph. My rig is a towing beast for the following reasons: 1) the motor is tuned by 5 Star and was dynoed at 425hp and 440 tq; 2) I run LT tires at 80 psi when towing; 3) and finally I am running a Wagner intercooler.
The biggest issue with the EB is intake temps. This has a huge affect on hp and tq. I monitor the engine using an Aeroforce Interceptor gauge. Before my engine mods, the intake air temperature would run about 30 degrees higher than ambient temp during the summer. Now my intake air temp runs about 8 degrees higher than ambient. There is a huge difference in low end torque.
