The torque curves with the GDE tunes are much broader and relatively flat from 2000-3400 rpm. This dramatically improves drivability and vehicle response in all conditions. This is achieved without a boost spike or a peaky torque curve to provide a more linear feeling when driving.
FUEL ECONOMY COMPARISON
The fuel economy improvements are considerable when driving a constant speeds or accelerating conservatively, roughly 5mpg improvement on the PD motor and 2mpg on the ALH motor. If driving aggressively it is feasible to maintain stock fuel economy with much more performance. Driving style has a significant impact on overall fuel economy.
The ECO tune has a smoother pedal map to help achieve the FE gains in the part load operation. The HOT tune has an aggressive pedal map to provide better response, but this tends to reduce the FE slightly.
