The torque curves with the GDE tunes are broader and relatively flat from 2000-3400 rpm. This dramatically improves drivability and vehicle response in all conditions.


The fuel economy improvements are considerable when driving at constant speeds or accelerating conservatively, with an average gain of 2-4 mpg. 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.
