That was absolutely an oversight on my part, and was truly embarrassing. Didn't check the filter (it even has the filter minder) and was towing the boat with a truck load of people up a highway on-ramp. Boost starts kicking up, and then *zero engine noise* except for the spinning of a turbo. And then it takes off again, and does it again. Limped back and got a buddy's truck and went fishing. I am probably in the "change it too often" group now.
