I'm in the uk and have a CAT C12 in a tipper -dump truck. no mpg loss at highway speed. To add another data point to your original question about boost - our C12 typically generates 22 psi boost under full load-full speed conditions. That is well above the green band. That is well above the green band. When the engine is stopped, the absence of boost pressure allows the plunger to rise to the open position, which allows condensation from the aftercooler to drain out.
