based on what you have said ... engine fan ecm programming issue or not, I would suggest you get that programming checked out by Mommaburt, Unilevers, etc. for a review if you value the life of your equipment. Odds are very strongly against you having a program that is even half-way right, nonetheless not downright destructive to that enigne and/or its turbocharger.

Would programming allow it to work for 9 months and then all of a sudden not? Not trying to be sarcastic, but I've had 0 issues with how the truck runs. The only engine concern I have is with the fan, and that's only been recently. The fan was operating fine, then all of a sudden it's not.
