Truck is on a full weight loss program. Livewire tuning with No Limit. Truck has 230,xxx on the clock but this noise only started within the last 5k miles. Sounds like electronic interference that I had on an old Chevy gasser I had in high school. The only thing I've done to this truck is add Fosgate speakers all around on factory amp but that's been 100k miles ago. What's odd to me is that it only happens in 4th and 5th gear. Doesn't matter if the nav radio is on or not. Looking for some help.
