I think there must be some other factor involved. I did a lot of research before I decided on the 3.5 Ecoboost; if you spend as much time on the F150 forums as I did you'll see there is almost no discussion of anyone having a turbo problem. Secondly, I have been a miner all my life - and the mine I worked for for the past 20+ years has a lot of the Ecoboost Fords. Granted, most of the pre-2015 trucks are the V8s but all of the newer ones are Ecoboosts. You can be sure I talked to the mechanics who worked on them to get their take before ordering my truck. Those trucks live in dirt all their lives. Lastly, I've had several diesel pickups with a turbocharged engine and not one has ever had a problem with the turbo. Heck, today I spent 6 hours working a turbocharged diesel tractor, in dust so thick it was zero visibility at times. As long as the filters are properly maintained dust should be no more of a problem to a turbocharged engine than to any other.
