Boost tube blowoff. Need help

The following issues is on my 06 6.0l listed below. I changed all the charge air cooler boots about 2 months ago with a set from Riffraff Diesel. I pulled my 15K 5th wheel several times in the last 2 months with no issues. About a month ago, I started hearing a different sound from the engine. It sounded like the turbo but was a cross between normal turbo whine and a screeching. It comes and goes and has no bearing on boost levels. I have heard it at no boost and all the way at 25 psi. Then the trouble started this weekend. I was pulling my 5th wheel up the hill (several 8000' passes) and the boot off the turbo blew 5 times. The metal boost tube just popped out. I had my daughter get a new boot from from with new clamps. Put the new one on and within 1/2 mile it popped off again. Put it back on and decided to make one more attempt at the pass. This time I kept my boost under 10 psi and was able to make it. I crested the passes at 10 MPH at times with this limitation but I was able to make it. So while I was camping, I got some silicone sealant and "glued" the tube in the boot. The truck sat all weekend and today I needed to drive home. Went up several of the passes and kept my boost at below 20 psi with no issues on the first three passes. The at teh top of the last big pass, it blew again. Had to limp home with a busted boot and kept my boost under 5 this time. So the question is, why is my boot keep blowing off? Is it related to the sound? I have no OBD codes and am now at a lose. Please help

Don't use silicone to 'glue' the boot to the tube. Clean the boot and tube very well and apply nothing before installing the boot to the tube. This is a dry fitting. The clamp will hold it.

I did install dry. I cleaned the boot (brand new) and the tube and it still blew off. I was just trying to get the truck home when I used the RTV.

Use hairspray. RTV has silicone in it and is slippery, even after it dries.

I've never had an issue with my BD boots even taken the turbo one off several times. They advertise that they will hold at 100 psi with their clamps.

Riff Raff boots do not have the internal bead that locks the boot to the groove in the pipe. I am also using BD Diesel boots and clamps.

I had the stock OEM boot blow off the turbo at very inconvienent times. Pulling a trailer thru a very congested highway and lose all power really sucks. I put BD on and not one issue since - that was 3 years ago. I really like their clamps much more robust than OEM.

I've been running the RiffRaff boots for a while now with no issues.

IMO, you need to figure out the screeching sound. As you posted, the boots were fine until you started hearing the new sound. Do you have a way to monitor boost? I'm not familiar with the BanksPDA.

Are you still running the PCV? Inside of CAC tubes oily? I had terrible problems blowing off the oem boots. They'd get oil soaked because of the PCV system allowing an 'oil mist' into the intake system. By the time Ford figured out they needed an oil resistant inner layer on the boots/hoses, I'd already moved to the RiffRaff boots.

Anyways, I'm betting you're overboosting....

If you have the stock plastic cold side tube, check it for cracks.

CIVICRR, The banks PDA is a monitor system that allows me to see several engine parameters. I can read boost and it has been around 15-20 when the tubes blew off. I still have the OEM PVC system as I have to smog in Ca. Yes the inside of the tubes are oily. I cleaned it off the best one can on the side of the road with glass cleaner. I replaced the factory OEM boots in June from degradation from oil and heat. I went to the RiffRaff boots. Those were fine for a almost two months. Then Thursday when this happened I put an OEM boot back on. Also the first time the boot blew today, the RTV was still intact as the boot ripped from the cured RTV.

JSM180-I have already had the plastic boost tube replaced with a metal tube duie to cracking.

So the question of the hour is what is causing the boot to blow off. I do not believe it is the type of boot as I had two different types blow off and at least one has been proven (OEM had 100K on it). So am I overboosting? Can these turbos overboost and still give a normal reading? I am leaning towards my turbo is failing internally and this is a result...
