It is broken, I drove mine HARD and never even came close to that low. No doubt the eco handles better. I had an eco PP and not have a GT PP and you can tell the eco is lighter up front. Highway I had mine up to 35 mpg. You will see a big difference in mileage. You will miss the sound of the GT though. The eco sound is just horrible to me. I would never do what you are considering but that is me.
