2011 with 80k miles, still full emissions.Truck started making an air horn type noise under acceleration and threw the CEL. Code shows to be P0299. As you might guess its also sluggish and underpowered. Any other things to check other that the plastic tube between the inter-cooler and the air intake valve? Haven't checked anything yet since its dark. Did a search in "6.7 Tech" and nothing came up.
