I have a question for the rest of you ecoboost owners. Mine has sucking sound from the right front side of the cab under part throttle acceleration. I don't remember this brand new as I started to notice it at about 1000miles. doesnt mean it wasnt there, I just never paid attention until then. I can't recreate it in the driveway, only on the move. It is bugging me and I have for the last 4000 miles just told myself it must be normal.

It's the turbos sucking air.

its just sucking in all the hot air from the 5.slow owners...

My turbo "sounds" seem to come from the right side of the cab as well. As I accumulate miles the sound seems to become more pronounced, but not bothersome. If I don't feel like listening to it, I simply turn on the stereo.

I'm guessing you're hearing the wastegates bleed off boost
