I REALLY should have read the owners book. So I am a very aggressive driver and I like the GT I just thought it was lacking in the power department (which it still is) but I just turned ECO off and WOW! I thought it was just how I drive with all the engine breaking, hard jumps to second, and problems downshifting. It is all gone. I could care less about MPG but the car is way more fun to drive, drove about 50 miles and I'm in love. Why haven't I done this sooner!
It is not mentioned in the owner's manual. It only explains ECO on automatic transmission version.
