I have a new 2023 Powerboost. On the freeway at 2000 RPM / 80 MPH, there is a faint low pitch bassy / boomy resonance. I’m not sure if this is normal noise with the 3.5L ecoboost/powerboost engines. I can’t pin point if it’s from the exhaust, tires, or something else. Does anyones truck do this? At 75 MPH it doesn’t exhibt this. As I go faster above 80 MPH it seems to lessen.
