Any small displacement engine without a turbo is a dog. Add a turbo to get more air in and more fuel can be added, therefore more power. Use two small turbos instead of one larger one and get the same boost with less lag. Not aware of any mod to accomplish this on the Eco and with the pain to change out the turbo it would be difficult to mod anyway. My truck will stay stock and I will not be pulling out into traffic without boost and torque to the rear wheels.
