Weird whistle

I just got back from a road trip towing my 5th wheel toyhauler. This is the second time I did this same trip since August. I heard the same noise back in August but kinda forgot about it till this trip. It's kinda hard to explain so I took a couple of videos with my phone. I don't feel like I have a lose of power so not sure what it is. I first started noticing it while coasting on a downhill with no throttle but today I noticed it while giving it good throttle on an uphill. Any suggestions?

You can hear it come and go on this one as I play with throttle.

It's there but hard to tell with the road noise. Best I can describe is like a cricket. More noticeable on second video when I am on/off the throttle.

Unusual noise, very hard to tell anything from that video. Unless someone has heard it before your probably on your own.

So, you are going to have to isolate it system by system, as it could be anything. It could be caused by anything from the a/c fan to something that is mounted loose inside the engine compartment or inside the door that only rattles at certain speeds and road surfaces. You need to consider everything and then start eliminating variables. Maybe a mechanics stethoscope could help you isolate the loudest area and you can dial it down from there. Just be the passenger, not the driver while doing that...

It's definitly in the engine somewhere. AC was off so don't think it is that, fan clutch is working fine, deltas are close to each other. If it were a cracked y pipe wouldn't I see an increase in EGT's and hearit all the time? Was wondering if it could be a bearing of some sort?

I'm wondering if it has something to do with the tune or higher elevations. I'm home close to sea level, I changed my tune to ID Extreme Street and can't hear the noise now.

Since I've been home I have switched to ID Extreme Street and have only heard it twice but it was very faint and only lasted a second or two when only being started for a few minutes and I was getting on an on ramp. Turbo bearing seemed good with no play in blades while pulling on it with my hands. What kind of noises would I hear if my turbo was on its way out?
