I recommend the Eco. I love mine. I heave heard of the 2011 -2012 having a small issue building condensation in inter cooler at low speeds in moist air. Mine acted up one time after driving through about 2' of water for a mile or so. Punched it a few times and it cleared up. It's not great on fuel like ford claims but its still pretty good for a 4 door 4x4 with 3:73. The duramax pre 08 is a Beast Dodge too but after the partial filters they all suck.
