Small pop sound when towing
Hello
I have a 2008 F250 diesel that I use for towing our 5th wheel a few times a month. When towing and going up a hill I give it more fuel to down shift in order to make the hill. Sometimes when the motor down shifts I hear a small pop sound coming from the engine almost like a backfire sound. Has anyone heard this also? Last time at my dealership they re-programmed the truck with a recommended Ford update but the truck stills makes the pop sound from time to time.
Thanks Eric

Could be a "turbo fart". Its excessive boost build up in the charge pipes and intercooler that "farts" back out of the turbo inlet and echoes in the filter box whenever the truck downshifts. Check out the numerous threads on "turbo fart" and see if some of those threads match up with what your hearing.
