CAC boots blowing off
I just finished putting a Bullet Proof Oil Cooler with remote oil filter on and now my boots are blowing off. I did put a new pig tail on the turbo actuator because the old one got crushed. Also new boots and clamps where installed. I have noticed while in idle I don't hear the turbo sound going from open to closed. before it did it all the time in idle. I did unplug the wire connector in idle and could hear the turbo sound change. The last time it blew the hose off the boost was at 25. I also noticed what I think is an exhaust leak on turbo when I let off pedal quickly. Any suggestions

Outside of the usual suggestion of using hairspray when you reassemble the boots to the CAC tube I don't know what else to tell you. I recently replaced the turbo on my '06 and cleaned everything up before reassembly. Dawn dish detergent on the boots inside and out as well as the CAC tube itself to get as much residue off as I could and let it dry out real well. If you're on good terms with the wife a shot of her hairspray on the ends of the tube and the CAC hookup and then a shot onto a paper towel to wipe on the turbo outlet. I didn't spray the turbo for fear of getting gummy spray all over and then having it cook on. Obviously tightening the clamps properly is in order although I don't have any torque setting for you. I squeezed until I saw the spring start to compress and then "turned it a little more".I haven't had any problems with mine blowing off but I don't often see 25 psi either. I haven't ever noticed any variation in turbo sound at idle either but I have a stock 6.0 without any tuning.

If the 25psi number is correct, they shouldn't be popping off. As noted above, getting all the oil off of the connections is very important. If your using the factory boots pay particular attention to the ridge inside it and get it lined up in the groove that it mates to before tightening the clamp. Also check the marking on the outside for proper alignment of the clamp. Aftermarket boots often don't have any ridges or markings so you have to take your best guess. (And clean everything up very well). I was popping my cold side lower connection after I went with the metal tube. Ended up double clamping the lower connection after putting it back on a couple of times, on the side of the road, while towing our 5th wheel. No more issues.
